BATH FURNACE Russian patent published in 2020 - IPC F24B1/189 

FIELD: heating.

SUBSTANCE: invention relates to heating devices on solid fuel used for air heating and steam production in bath-houses. Technical result is achieved by the fact that bath-house furnace includes upper plate, base, furnace unit with grate installed on grate plate and flame arrester, in which furnace channel has a narrow and a wide part, a narrow part of the heating channel is connected to the furnace unit, and in the opposite, wide part is located furnace door, wherein all connections of the furnace assembly are made through a tenon-groove and in all such joints a refractory cord and a heat-resistant sealant are laid, and the furnace channel itself is fixed directly to the furnace unit using a heat-resistant sealant and a refractory cord, a two-piece flame arrester is located under the smoke pipe and above the grate plate, wherein the flame arrester first part is rigidly connected through the tenon-slot with the front and side walls or through the tenon-slot with the front wall and is installed on the ledges located on the furnace unit side walls, and flame arrester second part is movably installed on ledges located on furnace unit side walls and on the flame armament first part.

EFFECT: technical result is the furnace design simplification, furnace processability improvement, furnace space hermeticity enhancement, increasing heat transfer of the furnace, possibility of regulating heat transfer of furnace, simplification of furnace transportation from production to place of implementation, possibility of replacement of any worn-out parts of furnace, reduction of weight of furnace.
