The device is distinguished by an upper burn-out, and it is capable of doing this evenly and not spending a lot of fuel. Therefore, this option is considered the most economical to use. The efficiency of the unit lies in the fact that fuel oxidation occurs due to air masses that are fed through the furnace door.
This provides a fairly productive heat release. As for the structure itself, it is the possibility of its conditional division into three parts.
- If you start the presentation with the bottom of them, then this is the case for laying the heat source (loading chamber);
- This is followed by a working zone in which the combustion itself takes place. This site is characterized as the place with the highest temperature;
- The last, highest level is the removal of combustible gases. In it, combustion products are burned and heat exchange is completed.
How to make a do-it-yourself oven
Creating a hearth furnace with wood with your own hands to choose a place, it is advisable to take into account its availability. The foundation should not be shared with the house.
- You will need a grinder, with which you need to carefully cut out the top of the metal barrel. The cut off element is useful in further work, so it is worth saving it.
- Further, in order for the structure to have stability, it is necessary to mount 4 legs for it. The channel material may be a channel.
- To perform the next step, prepare sheet steel, the thickness of which is 5-6 millimeters. From it you need to cut a circle, it should go inside the barrel. For safety from damage to the walls of the device, it is advisable to align the boundaries of the product.
- In the middle you need to make a hole (diameter = 20 mm).
- Then weld the pipe for the sake of venting air to the place where combustion begins.
- Attach 4 channel sections to the opposite side so that they are distributed equally over the entire circumference.
- Now we need to take the very component that was cut off at the beginning of all the actions, and make a lid out of it, having previously cut a 3–5 mm hole in it. And weld a strip to it from all sides. At the end, you should get a square shape product.
- From below, a hatch should be made, and a metal line should be drawn along its perimeter.
- Next is the installation of a pipe for exhausting smoke. It must be cut from the top edge by 50-100 mm.
- It remains for convenience to make handles on the lid and attach the pipe.
How to melt a hearth furnace on wood
- The oven must be loaded with pallets.
- The chimney is always heated. This will serve as a guarantee of stable traction. To do this, open the shutter for 6 minutes.
- The temperature must be constantly monitored with a thermostat. It is he who will reveal reliable information about the indicators.
IMPORTANT! It is forbidden to operate the oven for more than an hour.
