Furnace with metal hands

A homemade metal oven is perfect for heating a greenhouse, a garage, a working room and even a living room. For the assembly of the unit under consideration, metal sheets, barrels, pipes and even fire extinguishers of suitable size can be used. The procedure for making the furnace remains the same. Differences are present only at the initial stages of the preparation of the corps.

Advantages homemade metal furnace

The self-made metal oven has a number of advantages over brickbubbled heating units. Among the main advantages of the constructions under consideration are the simplicity of their design and the availability of raw materials.

It will not take a long time to make a simple metal stove - with the search( purchase) of metal sheets or iron containers of the appropriate size, there are usually no difficulties.

Furnishing of a metal furnace will require many times less financial investments in comparison with the construction of a brick heating unit. In this case, the furnace from the metal does not take up much space and very quickly heats up during operation.

Metal furnaces weigh much less than their brick counterparts, which eliminates the need to equip a powerful foundation. To further increase the efficiency of heating, a screen made of heat-resistant bricks can be laid around the metal heating unit.

Basic design features

The standard metal furnace consists of the following main elements:

• furnaces;
• of the ash-ash pan;
• capacity for stones( if the oven is created for use in a bath, in other circumstances it is possible to refuse such capacity);
• of the hot water tank( if necessary);
• grate grates;
• smoke exhaust pipes;
• doors for firebox;
• doors for ash-ash;
• latches for pipe.
  

  Two options for creating horizontal devices

Installation of grate grids is performed in the furnace structure above the blower. If there is a need to install a hot water tank, the tank is usually fixed directly to the stove, or slightly above it. At the same time, a chimney is usually passed through the vessel to heat the water.

The mentioned doors do not allow small embers, wood and sparks to fly into the heated space.

For the manufacture of a metal furnace body, sheet iron, barrels, pipes with a diameter of 50 cm and even large fire extinguishers can be used. The use of ready-made containers is more preferable.in this case the amount of welding work is significantly reduced.

Before using the tube to make the furnace, carefully study its condition for rust and other damage. If you find holes, put patches on them. In areas with the most serious damage, it is possible to make a door for an ash-pit or a furnace furnace.

Manufacture of a furnace from a metal pipe

The self-made furnace is manufactured in a few simple steps. However, the artist requires preservation of care and maximum accuracy in every event. The slightest inaccuracy can lead to serious consequences. For example, if the chimney is improperly configured, the stove may start to smoke the room, and a poor quality of welding work will cause leakage of the water tank.

Prepare a pipe with a diameter of 50 cm. The recommended thickness of the pipe walls is from 10 mm. In total, about one and a half meters of pipe is needed.

pipe The design in question includes a water tank, which makes the operation of the furnace more convenient and efficient. If you want, you can refuse to install the water tank. In this case, it is enough simply to exclude from the assembly manual the mention of the water tank. Otherwise, the furnace will be manufactured using the same technology.

First step

Cut the prepared pipe into 2 parts. The length of one of them( to be used directly for making the furnace) should be 900 mm, the second part( for the water tank) - 60 cm.

. The second step.

. Cut openings in the long pipe section for the arrangement of an ash-pit and a firebox. From the cut pieces of metal, prepare the doors for the corresponding holes. For this it is sufficient to weld loops, handles and latches to the workpieces.

Third step

Make slits in the sides of the housing for mounting the grate grate. You can weld the grate yourself from the fittings. The step of fastening the rods should be selected in order to ensure that thereafter the loaded fuel does not fall into the intervals between them.

Use the grate to weld the ears. Thanks to them and will fix the product in the slots.

Fourth step

In the back top of the furnace furnace make a circular hole for connecting the smoke pipe.

To the hole weld the horizontal branch pipe. To it in the future you will connect the main part of the smoke extraction structure. As a result, the chimney will be collapsible, which will make its cleaning much more simple and convenient. The recommended length of the chimney is from 4-5 m. The total length is determined by yourself. As a result, the outer part of the pipe should rise at least 50 cm above the roof of the building.

If necessary, install a heater and a water tank. These elements are usually included in the structure in the case of making a stove for the bath.

The heater is installed at the top of the furnace furnace. Install the tank at the minimum possible distance from the furnace. Usually one part of the tank is installed on the supports, the other - on the furnace furnace. Racks make from suitable and convenient for you materials. The main thing is that they are strong and as secure as possible.

It is not uncommon to use the option that the flue pipe is passed through the water tank, providing heating of the liquid. However, in this case, all welding operations must be performed as high as possible. Any slots will lead to tank leakage. As a result, water will enter the furnace and extinguish the fire.

If desired, you can independently make changes to the design of the oven, placing additional elements at your discretion.

It is recommended to equip the water tank with a crane.

To the bottom of the furnace weld strong metal legs. Installation of such units, as a rule, is performed on special podtopochnye sheets.

Around the oven lay a screen of fireclay bricks. The area of ​​the smoke pipe before going out to the street is also recommended to be bricked.

In places where the pipe crosses the house materials, place fireproof material, for example, based on asbestos. This will ensure proper protection of materials from fire.

The section of the chimney passing through the attic should not have valves, views or other similar elements.

The length of the horizontal sections of the chimney must not exceed 100 cm.

Recommendations for installing the

Furnace The metal stoves are installed in accordance with the regulations and rules of the current regulations.

If the walls of the building are made of wood, the distance between them and the oven should be at least 50-100 cm. If you wall the wall with refractory bricks, plaster or protect it with a thick metal sheet, this distance can be reduced to 20-30 cm.

The furnace and the chimney of the furnace must be at the minimum distance.

Light kilns can be installed without foundation, on a dense sheet metal. Relatively heavy units need an individual base of concrete or brick. The recommended height of the foundation is up to 200 mm.

Now you own the information necessary for the self-manufacturing of a metal oven. Follow the provisions of the presented manual, and the finished heating unit will be able to effectively cope with the tasks assigned to it for many years.
