Cooking rocket oven drawings. Independent manufacture of rocket type furnace

A practical heating device that is not inferior in its functional capabilities of traditional burzhuyk is a rocket furnace. Its in demand is to high efficiency, efficiency, availability of design and ease of manufacture. Collect such an aggregate at home can be even novice masters.

What is the stove rocket?

The reactive furnace received its original name due to the special design of the housing - the traditional form of the device is performed from the cuts of metal pipes, interconnected by the weld. Externally, it resembles a rocket installation. A simplified furnace model can be collected in a few hours.

The reactive heating device becomes as a result of the characteristics of the process of burning fuel material, when at a certain point in operation at high air supply in the fuel cell, the furnace begins to create a powerful buzz and vibration.

Important! A rocket furnace buzz is characterized by an irrational fuel consumption in the process of its combustion. Economical heating mode provides quiet operation of the heating unit.

Principle of operation

Despite the fact that the stove-rocket is quite simply arranged, the principle of its action is based on the following processes:

• Natural circulation of heated gases and air inside the channels. This means that the device does not require additional imaging, and the internal traction is created by the chimney system. The higher the chimney, the stronger the thrust.
• Diving of indispensable gases (the pyrolysis process) is carried out with a slight supply of oxygen into the fuel chamber. It provides a rapid increase in the efficiency of the device and the effective spending of fuel material during the combustion process.

The process of firebox furnace itself is as follows:

1. Fuel cuts are laid in the fuel compartment, and a register is performed.
2. Further establishes the standard operation of the furnace, at which the full heating of the vertical part of the design - the chimney pipe is carried out.
3. A sufficient heating of the furnace housing ensures ignition of volatile substances in the chimney and air loss in the upper part.
4. Natural thrust increases, which leads to the influx of air into the fuel compartment and an increase in the efficiency of the combustion process.
5. To maintain the full combustion of the fuel material, the furnace structure must be equipped with a special zone for the survival of pyrolysis gases.

A simple variant of the rocket furnace from the profile pipe is intended for cooking and warming up food, as well as for heating garden houses, cottages and hiking baths.

Advantages and disadvantages

Long burning oven has acquired special popularity and demand due to its positive characteristics:

• Available design and easy assembly. The easiest option of the furnace can be made at home from available materials in a few hours.
• Effective heat transfer using various types of wood fuel - firewood, chips, branches, bark and chips.
• Wide functionality. Ability to use the room for heating rooms, cooking and heating water.
• Full combustion of fuel with the possibility of surviving pyrolysis gases. This allows you to increase the efficiency and at the same time avoid carbon monoxide poisoning.
• The ability to re-bookmark the fuel without interrupting the workflow.
• No need to create forced thrust in the chimney system. A high level of self-regulation of the operating modes of the device.

The ergonomic furnace can be installed in any room, and lightweight structures do not require additional arrangement of the enhanced foundation.

Despite the significant advantages, such a unit is not deprived of some drawbacks:

• Lack of automation of the process of firebox. Homemade furnaces require constant control over the laying of fuel material from a person.
• High likelihood of burns with substantial heating of the metal structure.
• The device is not intended for heating residential buildings of a large area and stationary bath complexes.
• The design of the furnace provides for the use of well-dried fuel, as excess moisture can lead to a reverse thrust in the chimney.
• Eastern appearance of the finished device.

Design

A rocket type stove is represented by a fairly simple design, which is made of pipes of the required diameter.

The fuel chamber is a horizontal cut of the pipe in which the fuel laying is performed. In some cases, the furnace can have a vertical boot option. In this case, the device consists of three structural elements - two vertical pipes of different heights mounted on a horizontal pipe. A short cut pipe is a fuel compartment, a long cut - chimney.

To ensure an increase in efficiency, rocket furnaces may have additional structural elements:

• Fuel compartment (vertical or horizontal position) - to load fuel.
• Camera download (horizontal) - for combustion of fuel and accumulation of thermal energy.
• The subdivinal compartment is for the pyrolysis gases, which are formed when combustion of fuel.
• Outdoor furnace housing - for the heat insulation of the structure.
• Lena is a platform for relaxing in the lying position or sitting.
• The chimney pipe is to derive fuel combustion products and creating natural traction.
• The cooking surface is a horizontal platform for cooking or water heating.

Making your own hands

A self-made oven made of gas cylinder - an affordable version of a wood-burning furnace, which is provided for effective heating of rooms and economical fuel consumption.

To make a furnace at home, you will need:

• Empty cylinder case - 2 pcs.
• Metal tube to create a vertical chimney channel (diameter - 12 cm).
• Profile pipe for the manufacture of the fuel and a loading chamber (length 100 cm, section - 12 × 12 cm).
• Cuts of metal pipes: short by 80 cm (diameter - 15 cm) and a long 150 cm (diameter - 12 cm).
• Steel sheet (thickness 3 mm).
• Metal bars.
• Insulated heat-resistant material (perlite).
• Welding equipment.
• Bulgarian.
• Personal protection means - glasses and gloves.

To ensure the proper assembly of the furnace, it is recommended to prepare a working drawing with the exact dimensions of all structural elements of the device.

Step-by-step instruction for making a rocket furnace:

1. Three segments are cut from the profile pipe - two of them are 30 cm and one for a 35 cm for 35 cm. From the blank for a sun bed, the grinder is done by a rectangular hole for the fuel compartment and a semicircle for the vertical tube.
2. One 30-centimeter blank is cut longitudinally and welded to the fuel compartment to create an air channel.
3. The fuel compartment is connected to the pipe of hot welding.
4. From the reinforcement is made by grate, for the fuel chamber and the ash bar - doors.
5. Next is made a secondary chamber for downloading pyrolysis gases.
6. At the bottom of the cylinder is done by a hole for the fuel compartment. From the outside of the cylinder, the knee is fixed under the pipe with a diameter of 12 cm for chimney.
7. At the bottom of the pipe rolls the hole to clean the chimney.
8. From above on the pipe, a segment of a pipe with a diameter of 15 cm is saturated and welded with welding to the cylinder.
9. The free space between the two pipes is filled with insulation, the edges are closed with welded seam.
10. In the second cylinder, the bottom is cut off and the hole is brewed under the valve. It will be used for surviving pyrolysis gases.
11. Both cylinders are fixed with each other in a special groove with two welded rings so as to ensure the tightness of the finished design. The groove is condensed with a cord from asbestos.

Important! Before proceeding to the furnace of a homemade rocket furnace, it is necessary to carefully check the quality of the connecting seams and the tightness of the structure. In a working installation, air masses should not be incontrolled.

How to turn the rocket?

To obtain a maximum heating effect before the main laying of the fuel material, the rocket-type furnace should be heathed thoroughly. For this purpose, flammable materials are used: paper, chips, dry chips, sawdust, cardboard, reed or straw, which are placed in an open subpend compartment.

The heating system will lead to the appearance of a characteristic sound - a quiet or loud buzz. Next to the heated device, the main fuel laying is carried out to obtain the required amount of thermal energy.

The process of firebox itself is performed according to the following scheme:

• Opening the door in the subdivinal compartment.
• Laying fuel material to maintain the optimal combustion temperature.
• With the advent of the buzz in the furnace, it was confused closed until the moment of the complete transition to the silent mode of operation.

Important! If the closed air valve led to a decrease in the flame intensity, it must be opened to increase the thrust and strengthen the process of burning fuel.

Other types of rocket stoves

Based on the basic design of the rocket furnace, other options for heating devices with higher efficiency were created, which are designed for street use and internal use as a heating source and hot water supply.

Stove-stove

The device is designed for cooking and winter conservation, equipped with an extended hob calculated for several containers.

The distinctive characteristic of the rocket plate is that the vertical channel with the fuel chamber is located at the bottom of the hob. In this case, hot air from the furnace quickly heats the surface, and so that the plate remains as long as possible, the fuel gases accumulate inside the horizontal channel. The remains of the gas mixture are removed into the vertical chimney, connected by an angle with a cooking surface.

For convenience, the oven is equipped with stable supports, so it can be easily used on any surface both indoors and outdoors.

Water contour stove

A similar unit is equipped with a heat exchanger, which is connected to the heating system: radiators, pipes and water tanks. It is intended to create a full-fledged autonomous heating system for a small garden or country house.

Constructively, the stove consists of such functional elements:

• The vertical fuel compartment and the heat canal of brick are laid out on a solid concrete base. At the bottom of the design there is a coxy with a door to remove ash.
• Vertical steel channel with thermal insulation gasket protected by an outer metal casing.
• Heat shift unit with water circuit mounted on a metal casing.

A distinctive feature of the furnace is the creation of a water shirt when pipes instead of air circulates a liquid coolant, providing efficient heating of rooms.

Stove with Lena

Another embodiment of a jet furnace in everyday life is an arrangement of a comfortable design with a special platform for relaxing in a sitting or lying position. Lenhing can have a different form of execution - Topchak, a wide bed, a compact sofa, bench.

For the manufacture of the beds, bricks are used, cheek stone, clay mass with sawdust. The high heat capacity of the materials contributes to the accumulation of thermal energy for a long time, so that such a furnace is recommended to be installed in residential rooms.

According to the type of material used for the manufacture of the design, rocket furnaces are:

• Glinian-brick. The good heat capacity of brick and chammed clay contributes to the fact that such structures are well accumulated and highlight heat into the room. The temperature regime of fuel combustion in such furnaces can reach 1000 degrees. Clay-brick units require minimal maintenance, which consists in periodic coating of the body of the clay and eliminate cracks.
• Metal. Such devices are made of metal barrels, gas cylinders, fire extinguishers, pipes and sheet steel. The availability of materials allows to obtain a reliable and efficient heating unit. Hiking metal furnaces are extremely popular - "Robinson", "Lighting" or "Taiga". They differ in compact sizes, the possibility of installation in any accessible place and ease of operation.
• From girlfriend materials. Simplified rocket furnace designs can be made of the cheapest and affordable materials: canned cans, steel buckets and other tanks. Low power stoves can be used to quickly heating water in the field.

Mobile oven is a practical and cheap option for tourist hiking and resting in nature, which is provided for economical fuel consumption and ease of operation in any climatic conditions.

The stationary oven is an efficient and safe option for heating small areas, the organization of hot water supply and cooking.

With all its advantages, the jet design of the oven, made with their own hands, is not suitable as a complete heat source for the heating of a residential building. But to use the technical capabilities of the device to solve everyday tasks are quite acceptable.

A rocket furnace with your hands the drawings of which would certainly want to have in his archive most of the home masters, can be made, in principle, even within one day, since its design is quite simple. If there are skills to work with tools, reading drawings, the necessary materials are seized, then make a simple stove of this type will not be much difficult. It should be noted that it can be made from a variety of materials that will be at hand, but much will depend on where the furnace is planned to be installed. The oven rocket has a slightly different operational principle of operation, and can be both stationary and portable.

Stationary rocket furnaces are installed inside the house along the walls or on the platform set for cooking in the courtyard of the house. If the furnace is installed indoors, then it can drop the room, up to 50 square meters. m.

Mutable rocket furnaces are usually completely small and easily fit in the car trunk. Therefore, when departures, for example, on a picnic or a cottage, such a tuber will help boil water, and cook dinner. Moreover, the fuel consumption in the rocket furnace is quite small, as it can be used even dry branches, rays or grass bundles.

Operation principle of rocket type stove

Despite the simplicity of the furnace-rocket device, two principles of work are used in its design, which developers borrowed from other types of furnaces working on. So, for its effective work, the following principles are taken:

• The principle of free circulation of gases isolated from fuel on the created stoves, without the forced creation of chimney thrust.
• The principle of afterburning pyrolysis gases isolated during fuel burning in insufficient oxygen supply mode.

In the simplest designs of rocket furnaces, which are used only for cooking, only the first principle of operation can act, as they are enough difficult to create the necessary conditions for the flow of pyrolysis and the organization of gases.

To sort out the designs and understand how they work, you need to consider some of them alternately.

The simplest design of the rocket stove

To begin with, it is worth considering the simplest device of a rocket combustion rocket furnace. As a rule, such devices are used only to heat water or for cooking, and exclusively outdoors. As can be seen from the figure below - these are two cuts of the pipe connected by a right corner.

A horizontal part of the pipe is equipped with a firebox for such a design of the furnace, and fuel is laid. Often, the furnace has a vertical load - in this case, three elements are used to manufacture the simplest stove - these are two pipes of different heights, installed vertically and connected to the overall horizontal channel. Lower pipe and will serve as a firebox. For the manufacture of a stationary version of the simplest according to the design scheme, it is often used, installed on the heat-resistant solution.

To achieve a higher efficiency, the furnace was improved, and it appeared additional elements, for example, the pipe began to install in the housing, which enhances the heating of the structure.

1 - outer metal furnace case.

2 - pipe - heat chamber.

3 - a channel formed by a jumper under the fuel cell and intended for the free passage of air to the burning area.

4 is the space between the pipe (riser) and the housing, tightly filled with heat-insulating composition, for example, ash.

The furnace of the furnace occurs as follows. A light combustible material is first laid in the furnace, for example, paper, and when it turns around, pinch or other main fuel are thrown into the fire. As a result of the intensive combustion process, hot gases are formed, rising along the vertical channel of the pipe and the outgoing outwards. On the open section of the pipe and install a container for boiling water or cooking.

An important condition for the intensity of combustion of fuel is the creation of a gap between the pipe and the installed container. If her hole is completely overlapped, then burning inside the design will stop, as there will be no thrust that provides the air of the combustion area and raises the heated gases upwards. So that there were no problems with it, a removable or stationary stand for the container is installed on the top cutting of the pipe.

This scheme presents a simple design, on the loading opening of which the door is installed. And to create thrust there is a special channel, which forms the lower wall of the coil chamber and welded at a distance of 7 ÷ 10 mm from it plate. Even with the complete closing of the door of the furnace, the air supply will not stop. In this scheme, the second principle is already beginning to work - without active access of oxygen to burning, the pyrolysis process can begin, and the continuous supply of the "secondary" air will contribute to the allocated gases. But for a fully, the process still lacks another important condition - high-quality thermal insulation of the secondary survival chamber, since the process of combustion of gases requires certain temperature conditions.

1 - air channel in the furnace chamber through which it is carried out at the closed firebox door;

2- The zone of the most active heat exchange;

3 - ascending flux of hot gases.

Improved rocket furnace design

The design, intended for cooking, and for heating the room, is equipped not only by the furnace door and a second case, which serves as a good external heat exchanger, but also the upper hob. Such a rocket stove can already be installed inside the premises of the house, and the chimney pipe from it is removed on the street. After carrying out such modernization of the furnace, its effectiveness grows significantly, since the device acquires a lot of useful properties:

• Due to the second outer corps and insulation heat-resistant materials that thermally insulate the main pipe of the furnace (riser), hermetic closure of the upper part of the structure, the heated air saves a high temperature for significantly longer.

• In the lower part of the case, a channel for feeding secondary air was mounted, with success, carrying out the necessary subdivination, for which an open furnace was used in the simplest design.
• The chimney pipe in a closed design is located on top, as in a simple rocket furnace, but at the bottom rear of the case. Due to this, the heated air does not go directly into the chimney, and it is possible for circulation through the inner channels of the device, heating, first of all, the cooking panel, and then disperse inside the housing, ensuring it and its heating. In turn, the outer corps gives heat around its surrounding air.

In this scheme, the entire process of operation of the furnace is clearly visible: in the fuel bunker (pos. 1), there is a prevalence of fuel (pos. 2) in the mode of insufficiency of air supply "A" - this is regulated by the damper (pos. 3). Formed hot pyrolysis gases go to the end of the horizontal fire channel (pos. 5), where they are hurrying. This process passes due to good thermal insulation and the implementation of the continuous supply of the "secondary" air "b" on a specially prescribed channel (pos.4).

Further, hot air rushes to the inner tube of construction, called the Raiser (pos. 7), rises under it under the "ceiling" of the housing that is a hob (pos. 10), providing its high-temperature heating. Then the gas stream passes through the space between the riser and the external case-drum (pos. 6), ensuring the heating of the housing for further heat exchange with air indoor. Then the gases are lowered down and only after that go into the chimney tube (pos. 11).

To achieve maximum heat transfer from fuel and ensure the necessary conditions for the complete combustion of pyrolysis gases, it is important to maintain the highest possible and stable temperature in the register channel (pos. 7) for this pipe of the riser to enter the larger pipe of the larger diameter - the shell (pos. 8 ), and the space between them is tightly clogged by the heat-resistant mineral composition (pos. 9), which will serve as thermal insulation (peculiar lining). For these purposes, for example, a mixture of furnace masonry clay with chamoten sand is applied (in proportion 1: 1). Some masters prefer this space simply very tightly fill in sainted sand.

The design of this version of the rocket furnace consists of the following nodes and items:

• Closed fuel cap with vertical fuel loading with a secondary air receiver located in its lower part.
• The furnace passes into the horizontally located fire channel, at the end of which the pyrolysis gas is hurned.
• A hot gas stream rises along the vertical channel (a zoomer) to a hermetically closed "ceiling" of the housing, where he gives part of the thermal energy by the horizontal plate - the hob. Then, under the pressure of more hot gases, which goes next to the heat exchange channels, giving heat to the surfaces of the drum, and lowers down.
• At the bottom of the furnace there is an entrance to the pipe horizontal channels, running under the entire surface of the laying. Moreover, in this space, one, two or more turns of the corrugated pipe can be laid, in the form of a serpent, for which hot air circulates, heating the laying. This heat exchanged pipeline is connected at the end to the chimney pipe derived through the wall of the house outside.

• It should be noted that in the case of the manufacture of bricks from the brick, the channels can also be laid out of this material, without the use of metal cortex.
• Heated oven and laying, giving heat into the room, they themselves will serve as a kind of "battery", capable of measuring the area to 50 m².

The metal drum of the furnace can be made of a barrel, a gas cylinder or other durable tanks, and is also composed of bricks. Typically, the material is chosen by the masters themselves as it is financially possible and convenience of work.

A rocket furnace with a brick layer looks more accurately, and it is somewhat easier to install it than the clay option, but the cost of materials will be approximately the same.

What is needed for work?

The heating structure of the brick proposed for execution is designed on the principle of a rocket furnace. The size of the structure with standard brick parameters (250 × 120 × 65 mm) will be 2540 × 1030 × 1620 mm.

Our task is to fold out of the brick here's such an original furnace-rocket with a warm lay

It should be noted that the design is as parted into three parts:

• The furnace itself - its size is 505 × 1620 × 580 mm;
• Film compartment - 390 × 250 × 400 mm;
• Lenhing 1905 × 755 × 620 mm + 120 mm Headrest.

The following materials will be required to masonry the furnace:

• Red brick - 435 pcs;
• Standing door 140 × 140 mm - 1 pc.;
• Clear door 140 × 140 mm - 1 pc.;
• The furnace door is desirable (250 × 120 mm - 1 pc.), Otherwise there is a risk of smoking the room.
• Cooking plate 505 × 580 mm - 1 pc.;
• Rear metal panel-shelf 370 × 365 mm - 1 pc.;
• Asbestoset sheet with a thickness of 2.5 ÷ 3 mm to create a gasket between metal elements and bricks.
• Chimney pipe, with a diameter of 150 mm, with a tap 90˚.
• Clay and Sand for the solution or a ready-made heat-resistant mix. It should be noted here that 100 bricks laid placed on the width of the seam in 5 mm, 20 liters of solution will be required.

The design of this stove with a vertical load is quite simple, reliableness and effective in operation, but only if its masonry is performed qualitatively, in full compliance with the friend.

In the absence of experience in the work of a bricklayer and a cook, but a big desire to independently install such a heating device, it is necessary to progress, and to begin with the design "dry", without a solution. This process will help to deal with the location of the brick in each of the rows.

In addition, that the seams were the same width, it is recommended to prepare for masonry calibration wooden or plastic rails that will fit into the previous row before masonry the following. After grappling the solution, they will be easy to remove.

Under the masonry of such a furnace, it is necessary to have a smooth and solid foundation. Despite the fact that the design is compact enough, and its weight is not as large as, for example, in a Russian oven, the floor, walls are not suitable for its installation. In the case when the floor, though wooden, but very durable, before starting the masonry under the future furnace, it is necessary to be able to align and consolidate the heat-resistant material, for example, asbestos with a thickness of 5 mm.

Deoperation of a brick furnace-rocket with a bed:

Illustration	Brief description of the operation
	The first row is laid solid, and the brick must lie in exactly according to the pattern shown in the diagram - it will give a full strength. For masonry, you will need 62 red bricks. The diagram is clearly seen to the connection of all three furnace departments. The corners on the side bricks of the facade of the furnace are cut off or curly - so the design will look neat.
	Second row. At this stage, the internal chimney channels are laid through which the gases heated in the furnace will be held, giving the heat of the Lena bricks. Channels are connected to the floating chamber, which also begins to form in this row. The first brick wall, separating two channels under the layer, is cut off by the defect - this "surprise" will collect not burnt combustion products, and the clean door installed opposite the bevel will make it easily clean. For laying a number you will need 44 bricks.
	In the second row, the doors of the subpend and treatment chambers are mounted, which are necessary for periodic clarification in order of the ash chamber and internal horizontal channels. The doors are fixed with wire, which is spinning on the ears of cast iron elements, and then laid in the laying seams.
	Third row. It almost completely repeats the configuration of the second row, but, of course, taking into account the laying turns onwarding, and therefore 44 bricks will also need it.
	Fourth row. At this stage, the channels passing inside the bed, solid layer of bricks overlap. The hole of the furnace is left, and the channel is formed, which will die the hob and the discharge combustion products into the chimney pipe. In addition, the rotary horizontal canal, removing heated air under the laying overlap, is overlapped. For masonry, you need to prepare 59 bricks.
	Fifth row. The next stage is the overlap of the bed by the second cross-layer of the brick. Smoke channels and firebox continue to be removed. For a row prepared 60 bricks.
	Sixth row. The first row of the head restraint of the bed is laid out, and the part of the furnace begins to rise, on which the cooktop will be installed. It is still with chimney channels. For a number you need 17 bricks.
	Seventh row. The head restraint laying is completed, for which the bricks are used. The second row of the basics under the cooking panel rises. For masonry, 18 bricks will be required.
	The eighth row. The structure of the design of the furnace with three channels is performed. 14 bricks will be required.
	The ninth and tenth rows are similar to the previous, eighth, are laid out by the same scheme, alternately, followed by. Each of the rows uses 14 bricks.
	11th row. Continued masonry according to the scheme. This row will leave 13 bricks.
	12th row. At this stage, a hole for the installation of the chimney pipe is formed. The hole belonging to the stove is supplied with a cut-down brick for a smoother flow of heated air into the adjacent channel, leading to the lower horizontal channels located in the layer. 11 bricks were used on a row.
	13th row. The base under the stove is formed, and the central and side channel is combined. It is on him that the hot air will go under the stove, and then flop into the vertical channel leading under the bed. Located 10 bricks.
	13th row. On the same row is preparing the basis for laying a hob. To do this, around the perimeter of the space in which two vertical channels were combined, the heat-resistant material - asbestos.
	13th row. Then, a solid metal plate is placed on the asbestos gasket. In this case, it is not recommended to install a cooking panel with opening burners, since when they open, smoke can enter the room.
	14th row. The arranged hole for the chimney pipe is overlapped and the wall rises separating the cooking plate from the laying zone. For a number used only 5 bricks.
	15th row. For this row, lifting the wall, 5 bricks will also need.
	15th row. On the same row, in the continuation of the rear wall, a metal shelf is fixed next to the cooking panel, which can be used as a cutting board. It is fixed on the brackets.
	15th row. The picture scheme is well modeled, how the cooktop can be used. In this case, the saucepan is put precisely on the site of the plate, which will warm up first, as a hot air flow will be under it.
	After completing all the works described in the coaches, in the hole, from the back of the furnace, the chimney pipe, which is removed on the street.
	On the back, the design looks also quite carefully, so it can be installed both around the wall and in the middle of the room. Such a furnace is perfect for heating in the country house. If the oven and the chimney pipe is decorated with finishing materials, the structure can be an original addition, and very functional, for any private house. As you can see, the corner formed under the cutting shelf is very convenient for drying and storage of firewood.
	To fully consider the design, it is necessary to see its projection from the end side.
	And in the last figure it is well shown that it should turn out as a result of the work done, if you look at the furnace on the side of the Lenja.

In conclusion, I would like to especially note that the design of a rocket furnace can be called one of the easiest and most affordable for self-making, compared with other heating devices. Therefore, if a similar goal is set - to get a furnace in the house, but the experience in such work is clearly not enough, it is best to choose this particular option, since, eating it, it is difficult to make a mistake in the configuration of its internal channels.

Simple options for heating the room, heating and water are always popular, especially at homemade masters who seek to make such aggregates independently. Such structures include a stove rocket that works on firewood, and perfectly copes in the tasks assigned to it, and does not require complex materials for manufacture. Today we will dwell on the design of such an interesting heater, as well as provide drawings and videos in order to make a rocket oven with their own hands.

Principle of operation

Before you begin the manufacture of an aggregate, it is necessary to consider the principle of its work in detail. Immediately I would like to clarify that the rocket furnace for the house has nothing to do with the jet and flights into space. A similar name of the furnace was awarded in the people at the expense of an unusual appearance: the unit is very similar to the launched rocket and with the work of a characteristic buzz.

The buzz appears in the furnace only with a certain mode of operation, when too much oxygen is supplied to the fifuel. Please note that if your oven bursts too loudly or publishes unknown roar, this indicates incorrect, uneconomical and inefficient work. The correct operation of the rocket furnace is accompanied by barely audible rustle.

Portable rocket furnace Very often take with me a hike for heating food

Thermal units of this type, depending on the scope of use, can be divided into:

• Portable;
• Stationary.

The first is mainly used in hiking conditions, they are mobile, easily transported and do not occupy a lot of free space. The second type of construction is more capital. It is used to install indoors, for heating the room or to heal food.

The principle of operation of the rocket furnace is easiest to show on the example of the simplest tourist firebox "Robinson". The design is an outdated tube in the form of the letter "g".

In that part of the pipe that is in a horizontal position in relation to the surface of the Earth, hard fuel (firewood, chips) is loaded, then the fuel is set on fire from the vertical part of the pipe.

In the transition channel, a traction is created, which is enhanced as the fuel heated, and therefore, for efficient operation, it is necessary to overlap the air supply from the outside. If the air supply is not limited, the firewood will be wrapped, and no thermal energy will eventually be obtained.

Even the simplest rocket furnace is able to ensure the heating of water in a large capacity in a matter of minutes. If you make the right insulation of the top of the pipe, you can burn thick lanes in the device and heat the room of a large area.

Types of rocket furnaces

Depending on the type of design, rocket furnaces are divided into:

• A rocket furnace with water circuit (with proper arrangement is able to replace a full-fledged solid fuel boiler);
• Rocket oven from the gas cylinder;
• Rocket furnace "Fire-owner";
• Simple brick rocket with a layman;
• Hiking options made of metal pipes.

Advantages and disadvantages

The dignity of the rocket-type furnace can be attributed:

• High thermal return indicator, which in some cases reaches 18 kW;
• High efficiency;
• Superffective work, which is characterized by a complete burnout of firewood, coal and soot loaded inside;
• To ensure combustion, even waste of the woodworking industry will be suitable (sinters, leaves, blesses, branches, leaves, regardless of the degree of humidity);
• Economical combustion and small wood consumption;
• High temperature at the outlet (heating of high water capacity is carried out in a few minutes).

Together with advantages, there are disadvantages of this type of furnaces:

• Installation of a coil for heating water reduces the thermal efficiency of the furnace;
• Continuous combustion cycle makes it impossible to install a rocket furnace in garages and baths;
• The small size of the furnace does not allow a large amount of fuel at once, to ensure long burning, a constant lining of firewood is performed.

How to make a missile oven with your own hands

Many make a decision to establish a rocket oven at the expense of the ability to make it from the remedies. Such a furnace does not require expensive materials and components, while standing out among other wood-burning furnaces with the original design.

For the manufacture of the oven, it is enough to understand a little in the drawings and be able to work with your hands. Especially for home masters, we will look at several options for making a rocket furnace.

Profile

This design is highlighted in maximum simplicity, so it is from her that it is possible to begin work on the development of the technology of construction of rocket furnaces. With the right approach, the entire production process will take no more than 3-4 hours.

The manufactured furnace will have small overall dimensions and weight, which is why it is convenient to take with them in hiking and fishing.

We will consider a slightly complicated version of a rocket furnace, due to the additional detail, the process of further use of the unit will significantly eradicate. We are talking about a small metal plate with a grid, which is removed for convenient loading of firewood.

To make the furnace, you need to prepare the following items:

• Two segments of the square pipe with dimensions 15 per 15 cm (metal thickness - 3 mm). The length of one pipe is 45 cm, the other is 30 cm;
• 4 strips were 3 mm thick and 5 cm sizes;
• 2 Steel strips with a thickness of 3 mm and sizes 14 by 5 cm.
• Metal grille with dimensions of 30 per 14 cm. If the lattice of suitable dimensions failed to be purchased, it is possible to make it yourself from steel rods.

The hiking furnace rocket is performed in the form of a curved pipe cut

The furnace production includes the following steps:

1. We produce the markup of two pipes for a further cut of a grinder at an angle of 45 degrees;
2. We connect pipes with each other with cropped sides and weld;
3. At the top of the vertical pipe, we make 4 cuts on the corners, insert the prepared strips of steel in them, so that the cross is formed, weld the design;
4. We make a frame for a retractable lattice from the remaining steel strips, we put the lattice on the frame and weld;
5. Check the oven for performance;
6. When the unit completely cools, stain with its heat-resistant paint to give an attractive appearance.

The design can be slightly improved, welding a handle to the retractable grille.

Some craftsmen make a stove rocket directly on hiking conditions from two tin cans. Such a furnace gives the minimum amount of heat, however, it is enough for heating dinner or a glass of water.

From the gas cylinder

For the manufacture of a rocket furnace from a gas cylinder, the diagram of which is presented in the figure, it will be necessary:

• 80 cm steel pipe with a diameter of 158 mm and a metal thickness of 4 mm;
• 150 cm steel pipe with a diameter of 127 mm and a wall thickness of 3.4 mm;
• The profile pipe is 100 cm long, 12 by 12 cm and a thickness of the wall is 4 mm;
• 2 empty gas cylinders;
• Sheet metal;
• Steel rods;
• Material for thermal insulation;
• Metal pipe with a diameter of 12 cm for chimney.

Scheme of a gas cylinder furnace with sizes

The production process includes the following steps:

1. The profile tube is cut into two parts. One must have a length of 30 cm, the second - 35 cm. In the second tube, drink a hole for the furnace and under the vertical pipe of the future plate;
2. The remaining piece of the profile pipe is cut along, we weld it to the furnace (it will serve as a hole for air supply);
3. Weld the firebox to the vertical pipe;
4. We make doors for firebox and ash bar;
5. Check the performance of the manufactured structure (primary chamber), waiting for its cooling;
6. With the help of a grinder drink a hole under the furnace in the lower gas cylinder. We weld the pipe with a diameter of 120 mm, which will perform the role of chimney, in the bottom of the pipe, we do a hole for cleaning the chimney;
7. To chimney, weld a slice of a pipe a little larger diameter, to the cylinder we weld the firebox;
8. The space between the pipe and the surface of the cylinder is falling asleep perlite, which acts as a thermal insulator;
9. In the second cylinder, the grinder cut off the bottom, brew a hole near the valve, the design will perform the role of tank for gas ignition;
10. Connect all parts of the stove with each other.

A more detailed process of making a rocket furnace from a gas cylinder is considered on video.

From bricks

The scheme of the simplest rocket furnace is considered in the figure.

The simplest design involves the presence of 21 bricks.

For the construction of an improved design, about 20-30 bricks and dry clay will be needed.

From bricks fold the design, as in the picture. In appearance, it resembles a rocket that prepared for the start.

Clay is used to give the design of strength and stability

We check the oven for performance, wait until the bricks are cooled, and they are coated with their prepared clay. The manufacturing process is completed. As soon as the clay is completely dry, the furnace can begin to use.

Video: Oven rocket from twenty bricks

Long burning design

The most optimal version of the oven is a long burning - a stove with a laying. This design is perfect for heating a small room.

Long burning rocket furnace is a great option for housing heating.

The manufacturing process provides for the following steps:

1. The place where the furnace will be subsequently located, deepened into the ground by 10 cm, the refractory stone is placed in the resulting recess;
2. A formwork is installed on the perimeter of the masonry, the reinforcement grid is spilled;
3. The lower part of the future working chamber is placed on the same level with an installed formwork, the design is poured concrete;
4. The constructed part is left for a day until the concrete is completely frozen, the base of the furnace and the combustion chamber is formed;
5. The walls of the future oven gradually rise around the perimeter;
6. The bottom channel of the rocket furnace is stacked;
7. The constructed design is trimmed with bricks, except for places where the furnace and the racer will be located;
8. The capacity of the metal (the iron barrel or gas cylinder is suitable) is trimmed with a grinder on both sides, covered with primer and stains heat-resistant paint, the pipe is cut into the lower part;
9. A dischaust is welded to the chimney pipe, which will perform the role of the ash bar;
10. From the brick, the heat pipe in the form of a square is laid out;
11. In the resulting gap between the metal capacity and masonry, thermal insulation material is falling asleep;
12. The body of a future furnace is formed, all brick surfaces are cleaned with the help of clay, styling the future contour of the furnace-laying;
13. The overseas of the furnace is checked;
14. All the gaps are compacted, the shape of the laying is formed, saman is covered on top.

How to drown the oven

If there are no special preparation for mobile rocket furnaces, then in order for the durable burning oven worked at the limit of its capabilities, it is necessary to pre-warm. Such an event also reduces the degree of pollution of the chimney.

Protect the oven is the most suitable paper sheets, wooden chips and sawdust. The degree of heating is estimated at the resulting Gulu in the channel. Initially, the hum will be strong, this indicates a high rift and small temperature, according to the degree of noise reduction, you can talk about increasing the temperature in the furnace.

To warm up a rocket furnace, it is best to use small sins and sawdust

As soon as the noise began to decrease, the main fuel is loaded into the furnace. After 15 minutes, the flap begins to gradually close. The gap must be adjusted in such a way that it can be barely audible from the oven.

Successful designs of rocket furnaces in the network abound, while the authors are often guided more intuition than technical calculations. The main thing is to adhere to the "M-shaped" type of design, and then it all depends only on your imagination.

Be sure to check the overall operation at the preliminary stage.

If it is planned to make a stove rocket from the gas cylinder, then difficulties can not be afraid. Actions to create equipment from such a building raw materials are quite simple:

1. from the balloon, the volume of 50 liters is cut off the upper part to construct a kind of cap;

   Cylinder cuts up from above and below

2. focusing on instructions in the drawing, with each other, all the details of the product are welded, that is, a gas cylinder, a pipe with a diameter of 10 cm (future chimney), a pipe with a diameter of 7 cm (internal channel) and another pipe with a diameter of 15 cm (the fifth);

   Dimensions are indicated in mm

3. the space between the two pipes is filled with material that maintains heat, for example, sand, which was thoroughly calcined, that is, purified from organic substances;
4. to give the construction of stability, legs are welded.

For the construction of a rocket furnace with a layman, which implies the use of bricks, you need to act differently:

1. The zone for the arrangement of the pop-up deepen, removing 10 cm of the soil. The flue chamber is formed from chammed bricks. According to the contour of the manufactured structure, formwork is created. So that the base is durable, it is recommended to lay a reinforcement grid or metal rods into it;

   Platform solidifies about two days

2. The design is poured with liquid concrete. Then wait when the solution will freeze, and compells work. Bricks are laid by a solid line by creating a furnace platform. After that, the walls of the structure are formed, exposing several rows of brick blocks;
3. It is equipped with a lower channel of the design, while one line of bricks is laid across to overlap the flue chamber. The blocks arrange, leaving the vertical channel and open the furnaces open;

   Two sectors of the furnace at this stage of construction must be open

4. Find the case from the old boiler and cut off on it the upper and lower covers. At the bottom of the resulting pipe, the flange is installed through which the horizontal heat exchanger will be held. Details are required to connect with each other with a solid weld;

   Work requires accuracy

5. Inside the barrel insert the outlet, after which they take a brush on the metal and removed from the walls of the container rust. The purified barrel is processed by primer, but a little later - paint, resistant to high temperature;
6. The horizontal chimney with welding is connected to the side tap - the future asht. To facilitate its cleaning, a hermetic flange is mounted;
7. Lay out the heat pipe made of refractory bricks. In this case, inside the design, a channel with a height and width of 18 cm. When doing this case, constantly use the construction level, which allows you to control the verticality of the product;

   The height of the pipe is determined in advance

8. The heat pipe is covered with a protective casing, and the resulting gaps are cleaned with perlit. The lower region of the vertical channel is sealed with raw clay, the function of which is to prevent waking up heat insulating material to the floor;
9. From the boiler, on which the top and bottom were cut, form the fuel tank. To him necessarily weld the handle;
10. To improve the type, the design is treated with a saman smear consisting of wood sawdust and raw clay. The first component of the composition is also served as crushed stone in concrete, that is, prevents cracking of the stove walls. A saman smear is recommended to apply on top of a pelite backfill;
11. Create a facade of the furnace, for which out of stone, bricks, saman and sand lay the furnace contour. Announced side of the structure is filled with rubble, and the front-saman mixture that makes the surface perfectly smooth;
12. The previously created base put the casing made of metallic barrel. The lower nozzle of the capacity is directed towards the laying. The bottom of the design is treated with crude clay, which will ensure its tightness;
13. A corrugated pipe channel is supplied to the furnace chamber. It will serve as a link between the furnace and the atmosphere from the outside;

    At this stage, the oven looks almost over

14. The ovens are carried out, depending on the gases are derived from the horizontal chimney. After that, the heat exchanger pipe is connected to the lower nozzle installed on the red brick platform;
15. The furnace is complemented by a pipe to remove smoke. The place of the combination of chimney and the heat generator is sealing with refractory coating and asbestos cord;
16. Using clay and saman, laying the desired shape. Just pronounced only the horizontal portion of the design, which will then be used during the cooking.

    The oven functions as a whole system

Reactive device with warm laying

One of the variations of such heating units - a stove-rocket with a sleeping place. It is based on all the same principle of pyrolysis. The difference lies in the design of the heat exchanger. Long channels of the apparatus are made of non-combustible materials and interconnected. This design is placed under the plane of the laying.

The protrusion itself is a surface of clay, stone or brick, inside which hot air circulates through the heat exchanger channels. During the operation of the jet furnace, the gas obtained by pyrolysis moves along the pipes under the layer, is heated and excreted through the chimney located on the street. Its height reaches 3000-3500 mm.

The device of the furnace with the furnace is located near one of the edges of the bed. Often there is a cooking surface, with which a homemade rocket furnace can also be used for cooking.

The stone or clay bed of the bed is covered with wooden flooring or bamboo or straw mat. It is necessary for the user's comfort, because the layer serves as a sleeping place at night, and during the day - the seat. The peoples of Asia rocket oven traditionally used for meals, equipping the bed with a special low table.

It is important to note that such a kind of furnace device has quite economically spending fuel resources. For heating the unit, there is enough of the heap of medium in the thickness of dry branches

Due to the fact that the stove rocket from the brick holds the heat for a long time, natopiv once in the evening, all night can be enjoyed by the created comfort, without taking care of the next bunch of fuel.

The easiest way to make your own hands a small portable oven - Robinson rocket, whose drawing is presented below. Cutting profile pipes, metal for legs and stand, as well as welding skills. Moreover, compliance with the exact dimensions specified in the drawing is not necessary. You can take the pipes of another section, only it is necessary to reduce or increase them in proportion to the details were shaked with each other.

Drawing of an improved hiking stove Robinson with dunes from a profile pipe cut along into 2 parts

Note

Please note that the drawing shows a design improved by our expert. As it believes rocket, improvised dozen people are attached to it, where the secondary air for afterburning, falling into the pipe through a row of holes

Due to this modernization, the combustion intensity increases noticeably. For details on the work of the compact wood stove, see the video:

The most common options for large rocket furnaces are made from a gas cylinder or a metal double-toll barrel. It should be understood that these finished elements are used as an outdoor cap, and the internal parts of the stove should be made from a smaller diameter pipe or lay out from chamotte brick. Moreover, from the cylinder, you can make it possible to make a stationary heater with a small bed and the unit that can be moved.

Immediately it should be noted that the calculation of the thermal power of the rocket type furnace is rather difficult, since there is no uniform technique for this. It is easier to rely on the finished drawings of already working samples and make an assembly on them. It is only necessary to compare the dimensions of the future stove with the dimensions of the heated room. For example, for heating a small room, there is enough cylinder sizes, in other cases it is better to take a large barrel. Selection of internal parts for them is shown in the diagram:

Stove rocket from cylinder

In addition to the gas cylinder itself, the stove will take:

• profile pipe 150 x 150 mm for the fuel and boot hopper;
• steel pipes with a diameter of 70 and 150 mm will go to the inner vertical channel;
• the same diameter of 100 mm per chimney;
• insulation (basalt fiber density at least 100 kg / m³);
• sheet metal with a thickness of 3 mm.

For a master who owns the welding case, this work will not submit special difficulties. At the balloon should be cut off the top of the seam, afterverting the valve and filling it with the top water. On the sides on both sides, openings are cut out for the installation of the fuel and a chimney. The profile pipe is inserted connected to the vertical channel, which is output through the bottom of the cylinder. Further work on the manufacture of a rocket furnace is carried out in accordance with the drawing:

At the end, the upper part must be accepted into place, then carefully check all the seams on the permeability, so that the air does not come inside the furnace. After that, you can attach a chimney with a water jacket (if available) and start testing.

Important. To create sufficient traction, the top of the pipe should be raised above the level of the fuel tip to a height of 4 m

Masonry Rocket type heater from brick

This version of the stove will require costs for the purchase of chammed brick, the usual ceramic for a rocket furnace will not fit. The masonry is performed on a solution from chammed clay, this is also available. Previously need to dig a hole, the bottom of the bottom and pour the foundation with dimensions of 1200 x 400 mm and a height of 100 mm, as shown in the photo:

After the frost, the foundation is covered with a sheet of basalt cardboard and lead the combustion chamber masonry, bunker for loading firewood and vertical channel. From the end of the combustion chamber, you set the door to clean the ash bar. When the clay dried, the pit is falling asleep, and a pre-selected pipe or a small barrel with a diameter of 450 mm is put on the vertical channel. The gap between the brick masonry and the walls of the pipe is filled with a refractory insulation, for example, basalt cotton.

In the last stage, a cap from a large metal barrel with a diameter of 600 mm is put on the design. Pre-in its upper part is made a cut and put the pipe to connect the chimney. When the barrel turns over, it will be at the bottom. Further is the case of technology, it is possible to remove the chimney immediately out or build a launcher with smoke-turns. For this purpose, ordinary ceramic brick and clay-sandy solution will already be consolidated. Brick masonry co-masonry with a small bed is shown in detail on the video:

We make the furnace rocket

The easiest way to make a light hiking stove, depicted in the drawing, finding the following materials in the household:

• pipe steel round with a diameter of 133-150 mm with a length of 0.5 m;
• pipe profile section 14 x 20 cm, length 0.4 m;
• metal sheet with a thickness of 2-3 mm on beats;
• rod Ø8-10 mm for legs;
• trimming iron on the stand.

The vertical round tube is welded to the profile at an angle of 45 °, then eyelashes for legs are attached to the housing (they should easily be removed). Inside the inclined fuel is a grate grille, the cover is fastened outside. For the convenience of cleaning ash at the bottom, it is advisable to install the second door.

Council. Be sure to weld to the upper cut of the fire channel stand - gases should penetrate between the dunning of the dishes and the body, otherwise the "rocket" traction will not arise.

Drawing of an improved version of a portable oven

The design of the furnace can be improved by organizing the supply of secondary air inside the heat pipe. Modernization will improve the efficiency and duration of burning firewood. Drill on the sides of the hole on both sides, covering them with rocket "dunes" according to the presented drawing. As this stove functions, it is demonstrated on the video:

From the gas cylinder

For the manufacture of a furnace - the rockets will go with their own hands:

• round section pipes with transverse dimensions 70 and 150 mm; with a wall thickness of 4 mm;
• square Profiter 150-200 mm in diameter;
• chimney nozzle Ø10-15 cm;
• steel low carbon (brand ST20) sheet;
• tight basalt wool (80-120 kg / m3) or bulk fire-resistant materials, such as vermiculite or perlite gravel.

To start metal, cut on the blanks according to the drawing. Then you need to remove the cover from the propane balloon, after unscrewing the valve and filling the reservoir to the top water. The tool is an ordinary Bulgarian with a circle for metal.

Further assembly technology looks like this:

1. Cut the proftruubou along, retreating from the edge of 35 mm. One part will make the manufacture of the ash bar, the second - pissed.
2. Dinet the fuel and a heat pipe at an angle of 90 °, making the appropriate cuts. On top of the combustion chamber, ride the opening where the boot bunker is welded.
3. Cook a risser with a fuel tip, then put on the pipe from the pipe 150 mm, making the cutout below the width of the combustion chamber.
4. Install and equip the bunker for the wood laying. Secure the doors of the fuel and ash bar.
5. Pull the perlite sand between the walls of the shocking agent and the shell.
6. In the cylinder, make the side opening to insert the finished design. The lid is better to make removable.
7. Implement the final assembly and welcome the chimney nozzle.

In detail about the manufacture of a rocket stove from the cylinder will tell the master in the video:

From brick

The simplest rocket chickens for cooking can be folded from bricks without the use of the solution, as shown in the diagram with coils. Such a structure is not difficult to disassemble and move if necessary.

The furnace-rocket with a bed must be put on the foundation from concrete or a boob stone. Material is a ceramic or refractory brick, sand-clay solution or chamoten, respectively. The finished base is covered with rubberoid for the purpose of waterproofing, then the solid first row of bricks is placed. The further order of work looks like this:

1. Put the fively, putting bricks "on the edge". Similarly, make the camera overlap, leaving the mouth to load firewood and the riser.
2. Build the pipe of the well from 9 rows of stones installed "on the edge" with dressing.
3. Put on the Ryser pipe or tin buckets, formed cavity Push off the insulation or ordinary sand.
4. Install the barrel up the bottom, bringing the flue gas pipe from below.
5. Fold a brick layer of 3-4 horizontal channels.
6. Correction of barrels and laying with clay mortar.

Important. The construction is performed in compliance with the headquarters, painted

The length of the flue channels inside the bed is limited to a rocket furnace and an external chimney. It is better to withstand the total length of the gas ducts within 4 m. In order for the heater does not smoke back to the room, lift the top of the smoke pipe to the height of 5 m, counting from grate. How to build a brick stove - a rocket without barrels, look at the video:

Device and principle of operation

Rocket furnaces have almost nothing to do with the device of rocket engines or jet turbines. On the contrary, they are extremely simple structurally, in contrast to the above devices. The similarity is noticeable except that in a quietly noisy flame and high combustion temperature - all this is observed after the outlet of the stove to operate.

Consider the device of rocket furnaces - they consist of the following elements:

• The furnace is a vertical or horizontal area in which firewood is burning;
• Camera combustion (it is a fire pipe, a riser) - there is a process of combustion of fuel with highlighting a large amount of heat;
• Pissed - it is necessary for the correct work of the stove and launch the process of burning pyrolysis gases;
• Heat insulation - envelops the vertical part, forming a drum together with the case;
• Lena - used for direct purpose;
• Chimney - assigns combustion products into the atmosphere, creating cravings;
• Stand under the kitchenware - ensures unhindered heat care.

Depending on the type of rocket furnace, those or other elements may be absent.

Rocket furnaces with vertical fireflies (fuel hoppers) and pensions are the greatest efficiency and convenience - large volumes of fuel are placed here, which ensures long burning.

The most important part of a rocket furnace is a vertical drum. It is in it that the highest temperature is observed, as flames are broken here

In order for it to start working, it needs to be careful warm. Without this, the process of burning will be weak. To warm up, paper, cardboard, fine chip or thin branches are placed in the furnace. As soon as the system warms up, the flame in the drum will begin to burn with the buzz, which is a sign of exit to operating mode.

Rocket (reactive) furnace without pushed burns firewood by direct method. It is more simple, but less efficient. The model with a confusion supplies secondary air to the base of the riser, which causes intensive combustion of combustible pyrolysis gases. Due to this, the efficiency of the aggregate increases.

The furnaces in rocket furnaces are located horizontally or vertically (at any angle). Horizontal fireboxes are not very comfortable, as the firewood in them has to be signed by the combustion zone manually, on their own. Vertical flue cameras are more convenient - load fuel in them and do your affairs. As the lamps are combustion, they will fall down, independently moving towards the burning zone.

Features of working rocket furnace

1. Before loading the main fuel, the furnace needs to warm up. This more concerns large and multifunctional rocket furnaces. In them, without preheating, thermal energy will be used to be used.
2. To overclock the oven in the open pistened to put dry paper, wood chips, straw. A sufficient heating of the furnace can be determined by Gulu in the furnace, which will continue in the future. Then the main fuel, inciting over the acceleration, is then laid in the preheated rocket stove.
3. At the beginning of the burning of the main fuel, the door pissed out completely. After a while, as the chimney humus appears, it was pissed off until the rumble is replaced by a whisper. In the future, to assess the state of burning the furnace, it is also necessary to focus on the "furnace sound", the opening door pondered during sinking and covering with the resulting hum.
4. The greater the reactive oven, the smaller the hole for the flow of fresh air is necessary. It is advisable to use a separate furnace in such an oven.
5. Adjusting the power of the furnace operation can occur only due to the volume of fixed fuel, but not due to air supply.
6. With an independent manufacture of a large rocket furnace, its bunker should be done with a tightly adjacent lid, without lumen and cracks. Otherwise, a stable furnace operating mode will not be ensured, which is fraught with excess fuel energy.
7. Contrary to popular belief, the rocket furnace for the bath is not suitable for installation, since the furnace does not emit infrared radiation in sufficient quantity, which is necessary for heating the walls and recoil convection into air mass in the conditions of the bath. The oven rocket for the bath, theoretically, can only be installed using the width-chramzov furnace type, the characteristic of which is given below.
8. The garage missile oven presents a mobile furnace design that can quickly heat the room. The main element is the heating tank of the pipe.

Types of fuel

With proper assembly and operation, the rocket furnace can be stirred by any type of solid fuel, wood and its waste. For example, branches, leaves, firewood, coal, corn stems, cones, chicks of chipboard, fragments of furniture. You can load fuel into the furnace both in dry and cheese. This is especially important for its operation in natural conditions, where it is not always possible to find dry raw materials.

Types of stoves for different operating conditions

The oven rocket with water circuit, brick or metal, can replace the boiler. The heat exchanger here is arranged in the upper part of the heat pipe in the form of a stuffing water shirt. Inside the shirt there are jumpers for more efficient heat removal to the heat carrier. The design is extremely simple, it can heat the home ownership of up to several tens of square meters.

The rocket furnace for the garage can be made of an old puzzled gas cylinder or barrel. For this purpose, two holes are made in the selected container - one in the upper lid, and another on the side surface. M-shaped pipe is inserted inside. Having a small experience with the welding machine, all work will take you to maximum half an hour.

You can also make the furnace of the above-described rocket type made of segments of a square and metal pipe according to the presented drawing.

Also for heating the garage, the heating rocket furnace "Fire-owner" is suitable. This is a shop model manufactured from an aluminum corrugated pipe and ordinary sheet iron. It works around the same scheme and allows you to warm up a garage with an area of \u200b\u200bup to 30 square meters. m.

There are no drawings in the open access yet, so you can try to collect the oven "Floor" with your own hands on the basis of its photo. Also, it can be bought on the manufacturer's website.

We have already said that for heating large households, a missile oven of long burning with water contour will be required. Little home ownership From one room you can warm up a simpler stove with a layer - so you will save space on the furniture. It consists of the following nodes:

• Vertical loading firebox - lamps are placed in it;
• Locking chamber is a horizontal section in front of the riser (heat pipe), pyrolysis burning is happening here;
• Raiser with a cooking surface - a vertical section with a metal housing that moves heat into the room;
• Horizontal channels - they heat the lay, after which the combustion products are sent to the chimney.

A rocket stove for heating at home from one room is cooked by clay to get a smooth and comfortable layer - here you can lay a mattress or a small bedspread.

For hiking use, the simplest rocket-type furnaces are used made of metal pipes. They differ compactness, easily become burned and quenched, quickly cool and allow you to quickly prepare lunch outdoors. The main thing is not to rearrange with the amount of fuel loaded, so as not to burn the food with a high-temperature flame.

Operating principle

Despite the simplicity of the design, the stove-rocket implies the involvement of two principles of operation at once:

• free flow of wood gases through channels;
• pyrolysis is hurrying gases that are allocated during burning.

The simplest stove-rocket uses only the first principle of work, because for pyrolysis there is not enough conditions.

Neat rocket stove made with your own hands

First, consider the variants of jet furnaces used for cooking. In such a device, a short pipe, located horizontally, is used as a fuel, and then it is directed up. This is the simplest design.

The fuel laying in the rocket stove is carried out directly into the pipe, after which it is set. As a result, the stream of hot gases is formed, which is focused to exit the outside, and therefore strives for the vertical site.

On the pipe section, the container used for water or food is placed. Between it and the pipe there is a lumen so that the combustion products can go out.

Many are interested in why such a furnace is called a rocket. In the design, there is a rotated nozzle from which, when the device is running, the flame is broken. Hence the name.

Flame languages \u200b\u200bescape from rocket stove

Of course, warm the room with such an aggregate will not work. The rocket furnace should be supplemented with a heat exchanger, as well as channels for removing combustion products. To ensure high temperatures on the vertical part of the pipe, insulation of refractory material is performed.

Nozzle can be covered with a cap. This is necessary for high-quality heat selection. The bottom of the horizontal section of the pipe is created by the channel for feeding secondary air.

The modern version of the performance implies a slightly different design. Such a reactive furnace implies afterburning pyrolysis gases, which is possible due to the receipt of secondary air. In addition, the combustion products are harvested under the top of the cap, which increases the pressure to excessive. Over time, the heat is transferred to the outside through the pipe walls, which forces the gases to cool and go down. There they will be waiting for hot air, so they have to be directed into the space between the walls of the cap and the pipes, going into the chimney channel.

Application of a rocket furnace with a cap on the plot

Due to pyrolysis processes, efficiency is significantly increased. And thanks to the interpretation of gases, a self-regulating system is organized.

Jet furnaces, drawings of products

Rocket stoves are divided into portable and stationary. The first devices are smaller in size and have a simpler design. She reminds crushed letter "g". Fuel is laid in the lower crossbar. Thanks to the vertical form of the main part, natural traction occurs.

Photo 1. Drawing and ready-made metal furnace-rocket furnace with dimensions, on the left and top.

As the temperature increases, the device works more efficiently. Its power is enough to quickly heat water for cooking On several people. To make firewood not burned too quickly, you need to adjust the craving in the furnace. To do this, cover or close the fuel door.

Portablejet furnaces Serial are produced. The most popular models "Robinson" and "Lighting". Thanks to the simplicity of the design, they can be made independently.

Stationary devices are somewhat more complicated. In the cap, the air channels are made in such a way that the heated air first rises up. Transmitting heat inner walls, it gradually lowers down. Then passes into the chimney located at the bottom.

Photo 2. Drawing of a rocket furnace made of brick and metal barrel. Arrows show parts of the device.

Such a furnace is pretty Economical to useSince it is burning not only wood, but also pyrolysis gases. The chimney channel of the furnace is sometimes not removed from the room immediately, and spend inside the bed made of brick and / or clay. Such a layer heats the room to a comfortable temperature. The same design is manufactured From pipes of large diameter, barrels or bricks.

Important! The device needs preliminary warming before furnace. First ignite paper, newspaper or something quickly flammable

And only firewood is stacked in the heated firewood.

Stove-rocket long burning from brick

Since the brick accumulates heat, such devices are well suited for heating rooms. Taking into account the duration of burning, one fuel laying is enough By 6-8 hours of maintaining a comfortable temperature.

Sometimes the oven is made completely brick. Only accessories (doors) will need steel or cast iron. In other cases, the outer part of the furnace cap is made from a barrel or a wide pipe.

Attention! The brick oven requires a separate foundation that is not related to the building for the building itself. It is advisable to plan its location before the construction

Device from a pipe with water circuit, scheme

The design of the furnace is welded from iron pipes of different diameters.

If it is supposed to give a small room, the oven cap can be made from the spent Gas cylinder.

In the house more impressive sizes for these purposes iron barrel.

If you install the water circuit on the chimney of the oven, then you can get a long-burning boiler that will be good to dump the room.

Water circuit is usually made of gas cylinders.

"Robinson"

This is a simple and reliable hiking oven. She is capable pretty quickly (in 10 minutes) boost litters water. At the same time, the firewood does not need.

The design was designed in the last century, but due to its advantages is still used. "Robinson" is produced serially, but It is easy to assemble and independently.

"Flint"

Such a furnace is similar to the previous option. But the furnace camera in it shorter and located under a stupid anglein relation to chimney. Such a stove reminds on the shape of the overtaken letter "g".

Step-by-step instruction

Here is an exemplary procedure that should be followed in the manufacture of this furnace:

Fire manufacture

The firebox is welded using steel pipe or sheets. The cover of the furnace should be closed hermetically. It should be done from the steel sheet, on the perimeter of which the band from basalt cardboard is recorded with screws or ripples. For a more dense closing, the lid can be equipped with a screw clamping mechanism.

So the firebox and the ash tank look like in the simplest furnace-rocket

The ash chamber (in the diagram is indicated as Primary Ash Pit) separated from the main part of the furnace with a grate with a rod with a diameter of 8-10 mm. The grid must be installed on the shelves from the corner, which are welded to the inner walls.

The coil chamber door should also be hermetic. It is made from the steel sheet, to which the steel strip is welding around the perimeter in two rows. In the groove between these stripes, asbestos cord or basalt cardboard are placed.

It remains to welcome the heat pipe to the furnace.

Primary chimney

1. To the pipe that performs the function of the primary chimney, it is necessary to welcome the 90-degree tap and a small segment of the pipe, after which this M-shaped structure is placed inside the barrel or cylinder, that is, the future drum.
2. The removal with a pipe welded to it should be brought into one of the openings at the bottom of the drum so that the primary chimney is located strictly in the center. Recall that the upper cut of the pipe should be located at least 70 mm below the top edge of the barrel (cylinder).
3. After centering the primary chimney, its horizontal shank, which was removed in the opening in the drum, weld to its edges with a solid seam all over the perimeter.
4. After that, the shank of the primary chimney is welded to the heat pipe, and a tire weld to the drum from above.
5. To the second loot in the drum should be a short cut of the pipe, which will play the role of secondary ash bar. It needs to perform a window for cleaning. At its edges, you need to privify the studs to which the lid will be screwed down (we will remind you that we decided not to install the door in this place, since it is rare enough to open it).
6. On the perimeter of the cover with screws or ripples, the band from basalt cardboard should be fixed.

Installation of chimney

To the output of the secondary roller, we weld the horizontal part of the chimney, on which the layer will later be arranged. If the gas duct is expected to do from the metal, then first to the ash with a short pipe, and already to it - to connect with the help of a clamp corrugation.

At the final stage, an outer chimney is fastened to the horizontal gas duct.

Futher on the furnace

The metal part of the furnace is ready, now it needs to be properly plastered with thermal insulating and heat accumulating compositions.

The lining of the furnace unit (to the primary chimney) should be made by a mixture of furnace clay and a combat chamotte brick combat, taken in the ratio of 1: 1.

Futherovka primary chimney

Materials used for the lining of the primary chimney - light chamotte brick or river sand - are porous, so in open state they are quickly soaked in Nagar and will lose heat-insulating properties. In order to prevent this, the lining on the primary chimney is protected by a steel thin-walled casing, and from the ends are deceived by the furnace clay.

In accordance with the law of the square Cuba, the ratio of the volume and surface area of \u200b\u200bthe drum depends on its diameter, therefore the lining of the primary chimney depending on the size of the furnace is made differently. Three options are shown in the figure.

Variants of the lining of the primary chimney

If the lining is performed by chamoten brick, the cavity between its fragments must be covered with construction sand. If rich river sand is applied by alumina, it is necessary to resort to a more complex technology:

1. Sand cleans from large garbage (careful preparation is not required).
2. The casing falls asleep a layer of a small thickness, the trambes and wet it, so that the crust formed.
3. The following layers are embroidered in the same way. There must be from 5 to 7.
4. The sand lining is dried for one week, then the top of the chimney clay is shovel and the furnace production continues.

Last step, all parts of the furnace are deceived by the one. It is prepared from the following ingredients:

• clay;
• straw (14-16 kg per 1 m3 clay);
• sand (in small quantity);
• water.

The specified ratio of straw and clay is approximate. In some varieties of clay straw can be added more, in others - on the contrary, its quantity has to be reduced.

Construction of a brick rocket furnace

The Kamenka has similar technical properties as the metal structure, however, the construction of a brick rocket furnace is the process of time consuming, requiring additional financial costs and time.

Kap a stone stove-rocket should be made from a barrel. For safety and ease of use, the design of the furnace, except the cap, you need to lower down, digs the pit under the floor. The bottom must be sealing and pouring with concrete solution, simple words - to make a foundation. The thickness of the concrete coating should be more than 10.0 cm. In order for the foundation to become durable, and it could start the process of brickwork, it will be necessary to wait about 3 days until the solution fully solidifies. After this period, you can begin to build the walls of the rocket furnace.

For masonry, you can use only refractory building materials, namely:

• Fire-resistant clay solution;
• Refractory bricks.

After completing the styling, it should be waited until the solution hardens, and the design will become a holistic, durable and reliable. The iron barrel is installed on top of the fire channel, and the gap between the barrel and brick is filled with insulation. When processing the end, it is necessary to use the same fire-resistant clay solution. The biggest barrel is put on top, and the chimney nozzle is connected to the lower part.

How to make it yourself

Before making a rocket oven, you need to decide on the place of its installation, with the dimensions of the future design, develop a scheme. The laying technology is quite simple, any novice builder can master it.

The simplest design of the rocket furnace can be built of 20 bricks in the country area and use it for heating the food brought from home.

Choosing a place

Before construction, first of all, choose a place. Rocket type brick furnaces are recommended closer to the front door. In this case, the ash after cleaning will not need to be carried across the room, which will be positively affected on the overall dusting of the room.

It is also desirable that at the point of the pipe outlet there were no rafters located to the chimney closer than 40 cm. And yet, the oven should not tolerate the outside wall at home so that expensive heat did not go to the heating of the street.

Preparation of solution

The cement mortar under the influence of high temperatures is fast cracking, so only a solution consisting of clay and sand is used to masonry heating devices from bricks.

Their proportions are determined by the experimental way, depending on the quality of clay. Most often in the ratio of 1: 2 or 1: 3, and the higher the fat content of clay, the less it is added to the solution.

First, the clay need to soak, strain, and then enter the sand. The resulting mortar for the consistency should be a thick sour cream. Check the level of its viscosity in the following way:

• put in a mixture of a wooden stick or handle of the trunk;
• remove the tool and shook well;
• check the thickness of the nagward layer: if less than 2 mm add clay, more than 3 mm - sand.

It is necessary to approach the solution to the solution with full responsibility, as fill all the irregularities of bricks and ensure their solid grip can only a plastic mixture of the desired thickness.

An example of a brick rocket stove

Laying rocket furnace with a laying

The brick rocket oven, even equipped with a layer, has a small size. The order presented in the figures (below) allows you to assemble the design without the use of metal products. Iron will only do the doors. Subsequently, the housing can be deceived by clay to give it more rounded shapes.

After the completion of the masonry work, the homemade stove rocket should be dried, carefully, producing heaving low intensity. At first, no more than 20% of the firewood stands are laid in the furnace, and the device is attacked twice a day for 30 to 40 minutes

According to such a scheme, the stove is drowned until its outer surface is cleaned of raw spids. On drying, depending on the dimensions of the device, it may be necessary to be required from three to eight days. During this time, the room should be well ventilated, especially in the summer.

Acceleration of drying can lead to climbing masonry, that is, the device will become unsuitable for further furnace.

Varieties of rocket furnaces

In this section, we will look at the most common types of rocket furnaces used in hiking and stationary conditions.

Metal stoves

The simplest reactive stove on the wood is made of a M-shaped segment of a large diameter metal pipe. The horizontal part is short, it is a firebox. The combustion chamber is located in the vertical part of the pipe, firewood is actively burning here. In the horizontal section, a small metal plate is often molded, forming pondered. After heating, the rocket furnace goes to the operating mode, the flame escapes from its vertical section (heat pipe).

Such rocket furnaces are used to prepare food in hiking or street conditions - due to the small area, they differ in low heat dissipation, and the overwhelming part of thermal energy goes through the heat pipe. Teapots, frying pan and pots are put on this pipe so that the raging flame ensures their heating. To maintain traction at the top of the pipe, the stands are located on which the dishes are put - combustion products will be able to freely go out.

In order for a metal rocket furnace from a M-shaped pipe cutting pipe to be more efficient, it is equipped with a metal casing from an old barrel. At the bottom of the barrel, it was visible attended, and a heat pipe looks out of the top. If necessary, the internal volume is covered with insulation, for example, ash - it does not burn and keeps warm well.

Metal rocket furnaces with vertical fireflies are distinguished the greatest convenience, located at an angle to the heat pipe. Often, the fuel holes are closed with covers, the air fence in this case is carried out through pis. Sometimes the firebox is done in diameter more heat pipe to provide long burning.

Simple brick furnaces

The small-sized oven rocket from the brick is another simplest version of the rocket furnace with your own hands. It does not require cement mortar for its assembly, it is enough to lay bricks on each other to get at your disposal a comfortable brick street unit for cooking. In the Self-assembly section of rocket furnaces, we will offer you to familiarize yourself with the simplest companion for self-assembly.

The rocket oven made with your own brick hands can be used to heat households. In this case, a simple friend cannot be done - you will have to build a stationary option using a special cement solution. Spots for this much, you will only have to choose the appropriate option. By the way, individual variants of such furnaces provide for the presence of a water circuit.

Advantage of brick rocket furnaces:

• Simple design;
• Long-term maintenance of heat;
• The ability to create a comfortable warm laying.

Separate models are made combined, they use both steel and bricks.

Sophisticated rocket furnaces

The jet furnace for the heating of households or for the bath is highlighted. The main link here is still a riser (heat pipe) enclosed in a metal case. Its upper part can be used to prepare food, forming a peculiar cooking surface. The firebox is large to accommodate an increased amount of solid fuel. Metal, bricks and clay are as starting materials.

Based on the clay coating, the streamlined rocket furnaces are made of the wrong shape, which is well perceived by human vision.

There are projects of wood rocket furnaces, providing for additional modules. The schemes of their construction include small boilers for the preparation of hot water, cooking surfaces, water shirts and even small brass cabinets. Such stoves will help warm up home ownership and create comfortable conditions for human accommodation.

A rocket boiler with a water jacket, created on the basis of a wood-burning furnace, will help to warm up the multi-room building. It is equipped with a water circuit for heating the coolant. Additional convenience creates samples with layers - these lads are created on the basis of heat channels between fire and chimney pipes.

We collect a rocket oven with your own hands

The easiest thing is assembled by a hiking and garden version of the jet furnace. To do this, you do not have to purchase masonry materials and prepare a samana for coating.

Several metal buckets, steel pipe from a stainless steel for a heat canal and a small crushed stone for frighting - that's all you need to make a rocket oven with your own hands.

The first step is the cutting screws for metal holes in the lower bucket for skipping the heat pipe. It needs to be done at such a height so that the pipe is left for a crushed stone backfill.

The second step is to install in the lower bucket of the heat pipe consisting of two knees: short boot and long for gases.

The third step is to cut holes in the bottom of the top bucket, which is put on the bottom. The headband of the frying tube is inserted into it so that its slice is 3-4 cm above the bottom.

The fourth is the frustration of shallow crushed stone into the lower bucket on half of its height. It is needed to accumulate heat and thermal insulation of the heat canal.

The last step is to manufacture a coaster for dishes. It can be welded from round reinforcement with a diameter of 8-10 mm.

More complicated, but the durable, powerful and aesthetic version of the rocket stove requires the use of a gas cylinder and a thick steel pipe of the rectangular cross section.

The assembly scheme does not change. Gas removal here is organized in the side, and not at the top. For the preparation of food at the cylinder, the upper part is cut with the valve and the flat round plate with a thickness of 4-5 mm is welded into its place.

How does a rocket stove running

Although the "rocket" device is the simplest, it contains two principles of combustion of fuel borrowed from other solid fuel stoves:

1. Natural circulation of hot gases and smoke through the stove channels - the standard solution, as in the bourgeitogo;
2. Having frowning unburned gases (pyrolysis) with limited oxygen access to the combustion chamber.

The scheme of the simplest reactive stove, which is intended only for cooking, uses the natural burning of firewood - in the open chamber it is impossible to create conditions for maintaining the pyrolysis reaction and afterburning the short-lived gases.

Consider a simple design of a reactive rocket-rocket, which is traditionally installed in the courtyard in the open area. It can be quickly heated with some kind of water volume, or prepare lunch for a family on vacation. From the figure below it becomes clear that for the manufacture of such a sample, two segments of the cylindrical or rectangular iron pipe are required, which are interconnected by welding at an angle of 900.

The simplest device of rocket

The horizontal segment of the metal box is the horizontal segment of the metal box - firewood is laid there. Also, the loading of fuel can be organized and vertically - simply add a horizontal pipe vertical iron cylinder to which firewood will be loaded. Thus, the design of three pipes or boxes is obtained, the lowest of which (horizontal) will work as a firebox. In the stationary scheme, the simplest design of such a stove often uses the usual red brick, which is placed on the clay solution.

The efficiency of such a design cannot be called satisfactory, so the craftsmen have come up with another scheme that increases the effectiveness of the work "Rocket". The extension element of such an improvement is another pipe of a larger diameter (as you can see, all materials are available and cheap), in which the main pipe stove is installed (primary chimney). So you can increase the overall heating of the stove and the duration of heat retention.

Furnace Scheme with Insulated Raiser

In the scheme:

1. Outer housing from the pipe;
2. Pipe that serves as a firebox;
3. Channel for air output to the combustion chamber;
4. Insulated area between the case and the riser. The insulation can serve as the same ash.

Making an upgraded furnace Robinson

The model described in the previous section can be improved with the help of a door that is installed on the fuel bunker. But if you make a sash on the loop, it will simply fold up the top, which will not allow you to adjust the thrust. Such a detail can only be in the "closed" position or "open." Much more efficient will be the use of the flap moving vertically or horizontally. To install it, on the bunker you need to welcome small corners with a size of 10 × 10 mm or 15 × 15 mm.

In addition, the following embodiments of the furnace are noted:

• the fuel hopper can be made of thicker steel, for example 5 mm;
• round chimney replace the square;
• for a stand to use a different design: as an option, corners, balls or other elements that are at hand are taken;
• change the stand under the hiking rocket, for which a metal plate and fittings segment can be used for the manufacture of legs.

To make an upgraded oven, you will need the following materials:

1. Square tube with a cross section of 160 × 160 mm and a length of 400 mm. From it will be made a fuel.
2. Square tube with a cross section of 120 × 120 mm and 600 mm long. It is needed for the manufacture of chimney.
3. The five-millimeter sheet steel and a piece of reinforcement with a diameter of 7-8 mm. Of these, an element will be manufactured separating the fuel compartment and a confusion channel. The size of the part must be 300 × 155 mm.
4. Steel sheet 350 × 180 mm. Such material is necessary for the manufacture of a furnace stand.
5. Steel leaf size 160 × 100 mm.

Technology production of this model of a hiking furnace It is not fundamentally different from the creation of such structures:

1. The metal plate with a grate need to be welded to the walls of the bunker.
2. Then the rear part of the tank is attached, and the flue tube is on top.
3. When the whole design is ready, the metal stand is welding below, and an additional backup is made from a piece of fittings. You can use a part of the vertical pipe that remained after cutting.
4. The slices of corners are welded on top to the vertical tube, which will form a stand under the dishes. Its height should be 40-50 mm.
5. The hole in the fuel bunker must close the door on the hinges or the flap inserted into the corner.
6. The finished product can be experienced. If everything went well, the welds are cleaned, and the reactive furnace is covered with heat-resistant paint. This not only give the product a more attractive look, but also protects the metal from corrosion.

Reactive heating unit from propane cylinder

A rocket oven from a gas cylinder is a simple in the manufacture of a wood stove, which economically consumes fuel, effectively warms the room.

It is used for its assembly:

• empty cylinder from under propane (unit housing);
• steel pipe with a diameter of 100 mm (for smoking the chimney and vertical channel);
• pipe steel profile 150x150 mm (the fuel and boot hopper is manufactured);
• steel sheet thick 3 mm.

Making a gas cylinder furnace requires the use of a welding machine. If you plan to assemble such a rocket furnace with your own hands, drawings will help accurately observe the optimal dimensions of all structural elements.

Scheme of processes in rocket furnace

At the preliminary stage of work, a gas cylinder should be prepared - to unscrew the valve, fill the tank to the top water so that it is guaranteed to remove the gas pair from the capacity capable of exploding from the spark. Then the upper part is cut along the seam. At the bottom of the resulting cylinder cut the chimney hole, and in the bottom - under the combustion chamber with an attached fuel. The vertical channel is displayed through the hole in the bottom, the design of the profile tube is welded from the bottom side, according to the drawing of the rocket.

Attention! The sheet metal cover should be made removable and provide a non-combustible seal (asbestos cord) for reliable sealing. The flat cover is used as a hob.
. If the stove of the rocket from the gas cylinder is mounted on its own, you should carefully consider the quality of the welds and check their tightness - it should not be able to completely act in the working furnace

If everything is in order, you can set the chimney.

If a rocket oven is mounted from a gas cylinder on its own, you should carefully consider the quality of the welds and check their tightness - it should not be able to completely act in the working furnace. If everything is in order, you can set the chimney.

Important! The top of the chimney is required to raise 4 meters at a height relative to the level of the pop-up to provide the necessary traction intensity.

Such a furnace for the house is adjusted by the capacity of the fuel load. The reactive stove is introduced into the air supply mode through the flue chamber, it is adjusted by the lid of the bunker. Next to the unit constantly serves secondary air. This heating stove at the end of the flue process begins, since it is impossible to overlap the feed air, and the nagar is settled on the inner walls of the vertical channel. The cover of the housing is removable, so that you can remove it periodically.

Boiler aggregate

The long-burning boiler can be obtained if you mount the water circuit on the chimney of the stove made from the gas cylinder or other materials, but by the same scheme specified above. However, water heating in the circuit of such an aggregate will occur ineffectively, since the main part of the thermal energy is given to the air of the room and the tanks on the cooking surface.

Effective version of a rocket furnace made of metallic barrel

If you wish to create a rocket boiler for water heating with a high efficiency, you will have to sacrifice the cooking function. The rocket oven with their own hands according to the drawing below, can be mounted in a short time.

This will require:

• chamotte brick and refractory masonry (for mounting the base of the stove with the fuel);
• steel pipe with a diameter of 70 mm (for vertical channel);
• steel barrel (for casing);
• refractory heat insulator;
• sheet steel 3 mm thick and metal barrel (or pipe) smaller diameter than the casing (for the arrangement of water shirt and smoke channels for heating the water circuit);
• steel pipe with a diameter of 100 mm for chimney;
• capacity, pipes and connecting nozzles for the arrangement of the heat accumulator.

The rocket furnace with water circuit is characterized by the fact that the thermal insulation of the vertical channel provides the optimal magnification mode of pyrolysis gases, while all the heated air falls into the "coil" with a water jacket and gives the main part of the thermal energy, heating the heat carrier there.

Rocket stove with water contour

The heat accumulator will continue to supply the heated coolant into the heating circuit even after the cooled of the furnace itself. Water tank is supplied with a thick layer of insulation.

How to make a rocket stove with your own hands

He has several stages - selection of a suitable design; selection of materials and tools; Directly manufacturing.

Choosing a project

Choosing a suitable project, consider such factors:

1. Appointment of the furnace - whether only the preparation of food is required or also heated the room.
2. Available materials.
3. Approximate power. It depends on it, by how many portions of food or on what room the device is enough.

Materials

For brick design, you will need:

• chamoite (refractory) brick;
• refractory mixture for masonry;
• concrete solution (for base);
• mineral wool;
• asbestos;
• a whole barrel or an empty gas cylinder for a cap (not necessarily);
• The furnace doors - the furnace chamber and the ashbar;
• if the cap is brick - a thick sheet of stainless steel in the size of its cross section.

For finishing the furnace apply:

• refractory paint;
• clay;
• stones;
• etc.

For metal take:

1. Round metal pipe diameter about 150 mmand length no more than 90 mm (better about 60 mm).
2. Profiled (rectangular) pipe cross section 100-120 mmand length About threeround.
3. Instead of a rectangular pipe, you can take a sheet of steel thick 3 mm.
4. 3 nuts.
5. Steel rods, plates or long bolts for legs.

Reference.For the best thrust profiled pipe, take the face no more diameter round.

Preparation of instruments

For the manufacture will be useful:

• master OK;
• level;
• welding machine;
• bayonet shovel;
• metal brush;
• level;
• bulgarian.

Production, Dimensions of devices

Variations on this topic set. Consider the manufacture two fundamentally different types of reactive stoves. This is a brick oven with a bed, which is used in the room, and hiking, assembled from the metal. If necessary, changes are made, there are combinations of methods (for example, a heating and cooking device, but made of pipes covered with clay or stones).

How to make a brick oven with a bed

First step - Foundation device. A rectangular recess is turned up under it, which is then filled with concrete.

For strength it is better to pre-install the reinforcement. The base should be strictly horizontal.

After pouring the concrete solution staying bricks begins. The outer walls are located around the perimeter of the concrete site. The combustion chamber is formed. On the one hand, it is placed with a cooler with a hole for loading firewood. On the other, the air ducts go.

Important! Each row of bricks is also checked by the level. This is done in both planes - horizontal and vertical

In the combustion chamber also Leave a hole for cleaning from ashwhich closes the door. When this camera is ready, a metal barrel is put on it. The gaps are filled with insulation, for example, Mineral wool.

If the barrel is not used, it is installed on top stove for cooking. Under it put asbestos insulation.

Chimney is connected to the air duct channel and is displayed.

Then ready The device is decorated. For example, fuses clay and covered with paint. Another option is to leave brickwork.

RECTIVE FUND FOR HANDS

It consists of two compartmentsconnected to each other. To gather it, to start cut the pipes at an angle in 45 °. If the metal sheet took instead of the second pipe, cut it into such parts:

• two with the sides 300 mm and 150 mm;
• two - 300 mm and 100 mm;
• and one 150 and 100 mm.

Photo 3. Finished reactive hiking stove. The device is made of metal pipes.

Then weld them with each other. You will also need another plate for separating the fuel compartment, its dimensions 200 mm and 100 mm.

All fragments are weldedin accordance with the scheme. The round tube is fixed in the bottom of the rectangular and in the middle relative to the side.

From trimming reinforcement grate. It is convenient to make a pull-out to lay firewood and then sticking inside the furnace.

From the pipe screaming 4 rings. They are attached from above, so that the dishes do not overlap the hole for the thrust.

In the collapsible version installed legs. Nuts are welded below, in which long bolts are then screwed. There is another way. Ponds or trimming of steel sheet are welded to the bottom. It is less convenient in carriage, but there is no need for assembly.

When the design is ready, It must be painted. Only refractory paint applies. It will keep off from corrosion, and also covers the tracks from the soldering.

In this design, as in the above described, the principle of operation lies in the isolated fire and the direction of thermal energy in the right place.

Stage 1. Preparation of all necessary

For the preparation of a portable rocket furnace will be required:

• two tin tanks of different diameters;
• pair of corners;
• steel clamps Ø10 cm;
• stainless steel pipe for chimney;
• small-flower crushed stone;
• bulgarian;

scissors for metal.

Stage 2. Build construction

Step 1. From the smaller bucket, the cover is made for the design. For this, it is done in the chimney hole (the lid is not removed). "Petals" is better to be flexing inside - so the pipe will be more reliable to be fixed.

The lower half bucket is cut with a grinder.

Step 2. At the bottom of the other container, a hole for connecting the fuel can be cut. Tin is cut by scissors on the "petals" and bend inside.

Step 3. The forward flow is collected from the pipe and pair of corners. Then the pipe is inserted into the bucket and connects there with the "petals" with the help of a steel clamp. All, forwarding rocket furnace is ready.

Step 4. The space between the direct flow and the walls of the bucket is covered with fine-mellular rubble. The latter will perform two functions - thermal insulation and thermoaccumulation in the design.

Step 5. The second bucket (cover) is put on the reactive furnace.

Step 6. The hardware is bent for dishes.

Note! Instead of the burner, you can install three bricks. . Step 7.

It remains only to paint the design of the heat-resistant paint (preferably gray or black). For the casting will be used the output nozzle of the forward-point.

Step 7. It remains only to paint the design of the heat-resistant paint (preferably gray or black). For the casting will be used the output nozzle of the forward-point.

Among the variety of wood furnaces, such a thermal device, as a homemade rocket furnace, deserves special attention. It is characterized by an original design that does not require expensive materials and components in the manufacture of expensive materials and components. Make such a stove can anyone, even a little bit of working in the drawings and knows how to work with his hands. Our article should come to help such home masters, where it will be described about the design and principle of the furnace - rockets. Here will also be given recommendations for its manufacture from various materials.

Operation principle of a rocket furnace

Although the device of a rocket furnace is quite simple, but it successfully uses as many as two principles of operation borrowed from other types of solid fuel heating devices:

• the principle of hurrying wood gases allocated during combustion (pyrolysis);
• the principle of the free flow of gases through the channels (without motivating from the natural thrust of the chimney).

Note. In the simplest rocket stoves for cooking, including a portable type, only the second principle is valid, since it does not create favorable conditions for the flow of the pyrolysis process.

Initially, we will analyze the device for rocket stoves of direct burning, intended only for cooking food. Here the toproom serves a short horizontal section of the pipe, which then rotates up. The design is simple to disgrace, which is shown in Figure:

The fuel is laid in the pipe and is ignited, as a result of which an upward flow of hot gases appears, striving to climb along the vertical section and exit. Here on the cutting pipe and the container for food or water is installed. Of course, there is an absurpency between the pan and the pipe to exit combustion products. This is achieved at the expense of various metal supports.

For reference. The above-mentioned device of a rocket furnace is one of the first. It is precisely because of the nozzle with the flame escaping from it, the device received the name of the rocket.

Since it is impossible to heat the room with such an aggregate, the design of the heating rocket furnace was supplemented with a heat exchange device and canals for the flue gases. In order to maintain a high temperature on the vertical section of the pipe, it is insulated with any refractory material. Further, for intensive heat selection, the nozzle is covered with a cap, for example, a conventional metal barrel. At the bottom of the firing horizontal pipe, a separate channel for feeding secondary air is performed.

Now the principle of operation of a rocket furnace looks somewhat different. First, at the end of the horizontal fire channel, the pyrolysis gases are hurned due to the arrival of secondary air. Secondly, combustion products having a high temperature accumulate under the top of the cap (barrels), creating some overpressure. As heat transfer to the outward through the metal walls, these gases are cooled and rushed down.

Since the reduction of the cooling gases is supported by the new hot flow, they cannot fall into the same way, but pass through the space between the walls of the pipe and the barrels, which safely leaving the chimney channel. The flow of processes well reflects the scheme of a rocket furnace:

So, thanks to the pyrolysis of the KPD of the combustion of wood increases, and the use of free gas flow creates a self-regulating system that limits the flow of fresh air into the fuel. The air mixture is supplied as the combustion products are cooled under the hood, freeing the place for its new portion. The excess pressure of hot gases "ejects" the cooled part outward, so the operation of the furnace is little dependent on the presence of thrust in the chimney.

Effective selection of heat

Gases falling into the chimney channel still have a high temperature. It is impossible to throw them out in an advantage, everyone will understand that the efficiency of this installation will be too low. Using the fact that the oven rocket literally pushes the burning products outwards, the craftsmen invented 2 methods of selection of heat:

• passing gases through the channels arranged under the layer;
• installing a water circuit on the furnace.

The rocket furnace with water contour is made without a cap, the strength of the upward flow of combustion products is used in a multiple heat exchanger made of metal. It is not recommended to enter a coil with water into the stream of gases, it will last long due to too high temperatures. It will be more correct to make a water shirt with a metal fins inside the gas pipe, as shown in the diagram:

Another way is to lay out horizontal smoking channels from the brick directly on the surface of the floor and to arrange a chic glorified clay heated bed, connecting a rocket type furnace. Here it is important to the correct selection of the length of the channels, so that overpressure is enough for their overcoming, otherwise it will still have to take care of the organization of natural traction.

Advantages and disadvantages

Homemade missile ovens of long burning have many admirers, and for what reasons:

• simplicity and low installation cost: To build a similar heat device, you do not need to carry large costs for the purchase of expensive materials, fixtures and fittings. The experience in the bary is also required minimal;
• self-regulation and undepair to the natural thrust of the chimney;
• Efficiency of the furnace - the rocket is the value of the variable and largely depends on the design, the main thing is to maximize the thermal energy in the flue gases;
• fuel can be added "on the go."

Despite the attractiveness and simplicity of the unit, the heating of a rocket oven has its negative points. It is mistaken to assume that you can shove in the firewood firewood of any quality. Wet wood will not give the necessary temperature in the chamber, the process of pyrolysis will not flow. In the worst case, smoke from the furnace can stick to the room. Also behind the "rocket" need a permanent care, especially in terms of fire safety.

Machine-made rocket furnaces are unsuitable for a bath, because they give relatively few heat in the infrared range, which is very important for the steam room. The surface of the oven, radiating heat, have too small area and protruding the bath as it should not be possible.

For reference. As a portable heat source, a metal rocket furnace Robinson of factory manufacturing is often used. Masters-craftsmen and were not confused here and quickly upgraded this product, making the same, only with a grate grid.

Stove from the cylinder

This is one of the easiest options, for its implementation, you can use the drawing below. The cylinder from under the propane diameter of 300 mm will serve as an excellent cap, and the role of a steel pipe with a size of 150 mm will play the role of the fuel and boot hopper. The inner vertical channel is performed from a pipe with a diameter of 70 mm, and the chimney is 100 mm.

The design is completely welded, the pipes are cut off the required length, and the top part is cut off the balloon. Then the parts are welded according to the drawings, only the opening between the vertical pipes with a diameter of 70 and 150 mm is filled with a bulk thermal insulating material. In the role of such a perlite or vermiculite, in the extreme case - ordinary sand.

If there is an opportunity and desire to make a more powerful rocket furnace, then the standard barrel is used as a cap, then the dimensions of all parts are also increasing. The working inner tube is accepted with a diameter of 129 mm (or profile 120 x 120 mm), and the outer-size is 450 mm. It is difficult to choose a pipe of this diameter, so you usually find another barrel of a smaller capacity and cut off from it.

The entire rocket oven from the gas cylinder assembly does not differ in great weight, therefore it is not necessary to arrange a massive foundation for it. When the unit is placed on the floor, the legs are welded to it, and if the layout is subsequently planned, the design will have to be deceived by refractory composition, and then perform an outdoor lining. Then the basalt cardboard and the roofing sheet of roofing iron are laid on the floor.

Brick oven

On its device, a brick rocket is not much different from the metal, but requires large labor. The difference is that all fire channels of the unit are performed from chamotte brick, and the cap is made all from the same barrel.

The whole design, except for the protruding cap, is recommended to lower below the floor level, for which a shallow pit is digging. Its bottom is compacted, and then a small concrete foundation with a thickness of 100 mm is flooded by formwork. After it is frozen, the laying is starting, applying a solution of refractory clay. After the end of the masonry and hardening of the solution, the pit is falling asleep, and on top of the fire canal wear an iron barrel without the bottom, the cavity between it and bricks are covered with insulation.

The end end is failed in the same solution, and then the highest barrel is put on top - the cap. His lower part is welded a chimney nozzle, to clarify all sizes, the drawings of a rocket furnace are used.

Conclusion

With all his advantages, a rocket furnace made by its own hands cannot serve as a full source of heat for heating a whole home. Typing such construction makes sense when it is necessary to organize heating a small cottage or another such building, especially since the "rocket" is not afraid of periodic work.
