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

FIELD: heating; home appliances.

SUBSTANCE: invention relates to heating furnaces and can be used during development of furnaces and heating devices for cooking food and heating of premise. Furnace includes housing made 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 in form of container for food preparation. Heating element of the furnace is installed in furnace housing with annular gap between its walls and walls of the furnace housing. This 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 triangles attached with one side to housing inner surface. These triangles are arranged so that they form several annular levels located at different height. Some triangles are located between these levels at cylindrical Archimedean spiral. Device for fuel laying interacts with at least three ends of triangles arranged regularly in circle.

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