Rocket stove: do-it-yourself rocket, drawings and videos, long-burning rocket stove, for heating

The rocket furnace is widely known in everything as a heating construction for long burning on solid fuel. To achieve maximum efficiency I had to work hard. A liquid fuel stove is able to give all its energy, but wood is more difficult to process. To open the full potential of the tree, in the jet furnaces equipped with a chamber for afterburning gases.

The principle of operation of a long-burning rocket furnace

The Shirokov-Khramtsov rocket or jet oven did not get its name because of its connection with space. The point is in the form of the device and the noise that is created during operation, resembling the operation of a rocket. But this sound indicates improper use of the stove.

Types of long-burning rocket furnaces:

• Portable (mobile);
• Stationary (for heating).

The most popular rocket model is the Robinson. It is often used on hikes. Thanks to a small portable device, you can understand the principle of operation of jet furnaces. The shape of the furnace resembles the letter “L”.

If the oven is too noisy and humming during operation, then this mode is inefficient and expensive. Normally there should be a quiet sound, a little rustling.

The jet furnace has a receiving hopper. This is the horizontal part of the pipe. Thrust arises in the channel itself, and it is this effect that affects the intensity of combustion, the heating case. That is why it is advised to limit the supply of oxygen. Otherwise, the firewood will quickly burn out and all the heat will disappear.

The furnace operates on jet draft due to the natural flow of hot air. The higher the temperature of the walls of the furnace, the better the wood burns. This allows you to quickly heat water in a large capacity, which is indispensable in a road trip. If the pipe is equipped with thermal insulation, then after heating it is possible to burn thick logs.

Do-it-yourself rocket stove: advantages, drawings, disadvantages

If desired, the conventional furnace design can be improved. So the potbelly stove loses a lot of heat, but by equipping the device with a water circuit or brickwork, you can solve these problems. For all these manipulations make drawings.

The advantages of jet furnaces:

1. Simple and budget design. You can use improvised materials, without significant financial costs. All work can be done with your own hands, special knowledge and skills are not required.
2. You can independently control combustion by choosing the desired intensity.
3. High efficiency. In general, it all depends on the quality of installation. The main thing is to select the maximum energy from flue gases.

But such a simple and convenient design has significant disadvantages. So you need to select a special fuel for the stove. You can not use wet firewood, otherwise pyrolysis will not happen. The firebox may begin to smoke heavily, and all the gases will go into the house. In addition, the rocket furnace requires high security requirements.

The most popular portable model is the Robinson rocket furnace. It was modified and a grate was added.

Home-made jet stoves are not used for heating the bath. They are ineffective in infrared light, which plays an important role for the steam room. Surface structures have a small heating area, so they can not flood the bath.

Drawings of a gas cylinder and other types of a jet furnace

Long burning furnaces are divided into stationary and mobile. Mobile stoves are used in hiking, picnics, in nature for heating and cooking. Stationary are used for heating a house, farm buildings, greenhouses, and a garage. At the same time, 4 types of structures are distinguished.

Types of jet furnaces:

• Homemade stove made of metal pipes, buckets, cans;
• Jet design from a gas cylinder;
• Brick oven with a metal tank;
• Stove with stove bench.

The portable structure is equipped with pipe sections. The only difference concerns the installed partition for the ash pan. For the lower part can use the grate.

A gas cylinder device is more difficult to build, but significantly increases efficiency. For the installation of the structure, a barrel or gas cylinder is required. Firewood in the furnace is burned due to the influx of oxygen by loading through a special window.

The gases burn out in the pipe, which is placed inside the structure, due to the supply of secondary air. The effect is enhanced by warming the inner chamber. Hot air is placed in the hood, and then into the external chamber. Through the chimney, combustion products are removed.

To create traction, the top of the chimney is placed 4 cm above the loading window.

The combined model of brick and metal is a stationary structure. Due to the high heat capacity, the wood stove accumulates and gives off heat within a few hours. That is why residential buildings are heated by such a design.

The rocket launcher with a bed is an advanced device that is able to retain heat longer. Since part of the heat exits through the chimney, they increased its length. Due to the rapid excision of hot gases and a larger chimney, this problem was solved.

This produces massive stoves with a stove bench, which are similar to a sofa or bed. These are stationary devices made of brick or stone. Thanks to its unique design, the oven is able to retain heat all night.

Drawings of the Flint Furnace and other do-it-yourself models

It is best to make small portable structures with your own hands: the Flint and Robinson missiles. It is easy to carry out the calculation, and for work you will need to cut profile pipes and metal welding skills. Dimensions may vary from the drawing, it is not scary. It is important to keep proportions.

To increase the intensity of combustion, it is advisable to add improvised nozzles to the design. Secondary air for afterburning will flow there.

Stationary rocket furnaces are made from a gas cylinder or metal barrel. These elements play the role of a housing. Inside, the stove is equipped with smaller pipes or fireclay bricks. From the cylinder, you can make both a stationary unit and a mobile one.

Scheme of a continuous combustion furnace:

• Chimney;
• Cap;
• Insulation;
• Loading hopper;
• Combustion zone;
• Afterburning zone.

Making a rocket furnace calculation can be difficult, because an exact technique does not exist. Pay attention to proven finished drawings. It is necessary for a particular room to determine its size of heating equipment.

DIY assembly of a furnace for heating

The construction of the furnace begins with preparatory work. First you need to determine the place of construction. He is chosen, focusing on the requirements that relate to solid fuel structures: wood or coal.

When you have decided on a place, you need to properly prepare it for construction. The wooden floor under the stove is dismantled. They dig a small pit and ram the bottom.

In a small room, a jet stove is placed in a corner. The loading hopper occupies one side, and the lounger the other.

A barrel or cylinder must also be prepared for installation. To do this, they cut off the lid and tap. Then clean the structure. Next, prepare a solution.

Stages of the construction of a jet stove with a stove bench:

1. The bottom of the dug hole is laid out with fireclay bricks. On the contour of the recess make the formwork. Perform reinforcement.
2. Spread the base and pour concrete. After a day, when the concrete hardens, further work begins.
3. From fireclay bricks lay the base of the stove. Raise the side walls, make the lower channel.
4. The combustion chamber is blocked by a brick. Two holes remain on the sides. One is intended for a fire chamber, the second - for a vertical pipe (riser).
5. The metal case is equipped with a flange into which the horizontal channel of the stove will enter. All joints must be airtight, well sealed.
6. A lateral branch, which serves as an ash pan, is attached to the horizontal pipe.
7. They make a heat pipe out of brick. As a rule, it is square.
8. The heat pipe is equipped with a casing. The gaps are filled with perlite.
9. Mounting the cap is done from the cut off part of the barrel or cylinder. It is equipped with a pen.
10. Equip the furnace body with brick or stone.
11. Equip the front of the furnace. Spread the necessary contour.
12. A prepared barrel is placed on the base. The lower part must be sealed with clay.
13. Using a corrugated pipe, a channel is formed connecting the firebox with the street.
14. The pipes of the heat exchanger are connected to the lower pipe.
15. Install the chimney. All elements must be sealed using asbestos cord and refractory coating.

Next, give the stove the shape of a stove bench. An external chimney is equipped with a trap for burning and tar. When all materials have dried, you can test the design.

Advanced Water Loop Rocket Oven

A long burning boiler can be obtained by equipping the stove with a water jacket. Water heating may not be effective enough. The fact is that the bulk of the warm air enters the room and containers on the hob. To create a rocket boiler, you must abandon the possibility of cooking on the stove.

Materials necessary for equipping a stove with a water circuit:

1. Fireclay bricks and masonry mortar;
2. Steel pipe (diameter 7 cm);
3. Barrel or cylinder;
4. Insulation;
5. Sheet steel and a barrel of smaller diameter than for the case, to create a water jacket;
6. Chimney (diameter 10 cm);
7. Details for the heat accumulator (tank, pipes, connecting pipe).

A characteristic feature of rocket furnaces with a water circuit is the isolation of the vertical part provides the burning of pyrolysis gases. In this case, warm air is sent to the coil with a water circuit and gives off heat to the stove. Even when all the fuel has burned out, warm air will still be supplied to the heating circuit.

Jet stoves are widely known among the people. They were used even by Korea, China, England and the population of Japan. The Chinese stove differed from the others in its ability to heat the entire floor. But the Russian counterpart is in no way inferior. Thanks to useful innovations, the stove is able to keep heat for a long time.
