FIELD: power engineering.

SUBSTANCE: furnace comprises a body with walls and an upper cover, where a combustion chamber with a combustion area is installed, and channels are arranged for air supply into the combustion area of the combustion chamber, as well as the channels for combustion products discharge from the specified chamber connected with a discharge pipe. A door with a lock with locking and stop elements is installed as capable of rotation in a frame installed on the body. In the upper part of the furnace, between the combustion chamber and the exhaust pipe, there is a screen installed, preferably, a profiled one, to form a cavity limited with the upper cover of the furnace, side elements of the furnace body, preferably with furnace walls, and the specified screen. In the screen there are windows in the form of slots, preferably in its peripheral zone, which connect the combustion chamber cavity with the specified cavity using horizontally aligned channels. Specified channels open into the specified cavity towards each other, and there is a swirler installed between output parts of the channels.

EFFECT: increased completeness of fuel combustion, heat recovery and prolonged duration of furnace operation with invariable fuel consumption.
