FURNACE Russian patent published in 2016 - IPC F24B1/26 F24B13/02 

FIELD: heating; home appliances.

SUBSTANCE: invention relates to heating furnaces and heating devices for cooking food and heating of the room. Furnace includes housing in the form of hollow cylinder, combustion chamber with fuel laying device and fuel loading door arranged inside the housing, a heating element located above the combustion chamber, made up of tank for food preparation. Heating element of the furnace is installed on the furnace housing with annular gap between its walls and walls of furnace housing, the above gap acts as a smoke stack. Device for fuel laying is made in the form of a circle with radial slots on the periphery, having the possibility of vertical and angular displacement. Supports for fixation of the device for fuel laying at required height are made in the form of inequilateral right-angled triangles attached to housing inner surface by its elongated side. Said triangles are installed so that they form several levels, located at different height. Ends of triangles at each level are located in one plane. Length and width of each radial groove exceeds the length and width of flanges of these triangles interacting with fuel laying device.

EFFECT: technical result consists in simplified design and improved conditions of heat transfer from combustion products to container for food preparation.
