The cost of energy that is tirelessbecoming more expensive every year, forcing us to look for more acceptable options. And the laying of the same pipeline to a country house sometimes results in such amounts that it is sometimes cheaper to build another cottage. Help in solving the problem with heating can be a self-made long-burning stove. You have probably heard about similar solid fuel boilers, which in recent years have become just wildly popular. Their problem is that not everyone has the desire to buy something similar for a country house, which is used irregularly in winter.
Unlike conventional wood boilers, which fornormal functioning need sufficient oxygen supply, a homemade long burning furnace is based on the exact opposite principle.
Simply put, the fire burns on top of the chamber,providing a very long and energy efficient process. Another advantageous difference is that the supply of the necessary (albeit in smaller quantities) for the combustion of oxygen is not from the room, but from the street.
Of course, the device can be welded fromsheet metal, but this method is associated with a number of difficulties. First, you need a good welder. Secondly, sheet metal of sufficient thickness is now expensive, and there is no place to get it.
А потому самодельная печь длительного горения may well be made of a metal barrel. But much better option with an empty gas cylinder. The thickness of its walls is greater, and the quality of the seams is much higher. This means that such a stove will serve for a long time.
We cut the barrel, giving it the shape of a cylinder,open on one side. In the upper part of the side cut a hole in the diameter of the future chimney. Since the furnace for giving long burning is unlikely to be used in the winter period, its design can be simplified as much as possible.
Next you should make and mountmetal piston. We take a piece of metal, the thickness of which must be at least 4 mm, and cut a disk out of it. Its external diameter should coincide with the internal diameter of your furnace, but you need to leave a certain margin, given the thermal expansion of the material.
All self-made furnaces for long burning must be thoroughly boiled, as a leakage will lead to a decrease in efficiency.
Every kind of wood is poured into a barrel on top.junk: trim boards and branches, sawdust and small chips. To speed up the ignition process, you can lightly pour them with waste oil. We ignite the fuel, after which we mount the piston with the air supply pipe welded to it. Put the cover.
All! Your self-made long-burning stove works. As the fuel burns down, the piston will lower under the weight of the pipe, preventing too much burning.
