The “gluttonous” boiler with a east european pedigree Buran 20 is used to heat buildings with a total area of about 100 m². It functions on the principle of upper combustion — the fuel is burned in a thin upper layer, and as it burns out, the fire gradually descends.

Long burning

A similar principle of combustion provides up to 30 hours of autonomous operation of the boiler on one tab of firewood. When using coal, sawdust or peat briquettes as fuel, the specified time can be increased up to 2 days, and when loading coal — up to 5 days in a row. Heated air is supplied to the top layer of fuel from a special chamber. Then the air distributor gradually lowers down and always keeps at the level of the burning fuel.

Operating data

The operating data of the boiler provide heating the coolant to a temperature of 90 °C at a maximum pressure in the heating circuit of 1.5 bar. In emergency situations, namely with a strong increase in pressure, the boiler will not explode, but will shrink inward. A distinctive feature of the early versions of the model (until 2017) was the absence of a bottom, but the new generation Buran 20 already has it.

Distinctive features

An important difference between the boiler and analogues is the presence of a large middle door, which allows you to load the fuel as tightly as possible. The movable air heating chamber also adds convenience in handling the model, which ensures easy and quick cleaning of the boiler from sticking deposits. Finally, it is worth noting the fact that Buran 20 is a non-volatile boiler, however, instead of a thermomechanical regulator, it can be equipped with an electronic control unit with a boost fan, which, in turn, will require connection to the power supply.
