FURNACE Russian patent published in 2009 - IPC F24B1/24 F25B5/02 

FIELD: heat engineering.

SUBSTANCE: invention relates to furnaces' structure and can be used for equipping of bathhouse, for heating of house, for food preparation. Furnace contains case, fire chamber with ashpit, chamber with heat-accumulating loading, fume-collecting chimney, connected to fire chamber and outfitted by damper. Lower fire chamber of furnace it is implemented cavity. Furnace is outfitted by additional chimney, installed in fire chamber vertically in space between furnace case and side wall of chamber with heat-accumulating loading and communicated with specified cavity, herewith axis of additional chimney is shifted relative to axis of fume-collecting chimney. Between furnace case and chamber with heat-accumulating loading it is implemented gas flue, connected to specified cavity, where it is located eddy generator- volute, connected to additional chimney, herewith top opening of additional chimney is connected to fume-collecting chimney with the ability of smoke fumes movement at closed damper by gas flue, cavity, volute and additional chimney. Furnace is outfitted by air duct in the form of pipeline, located in volute and additional chimney lengthwise its axis and outfitted by valve at the end of pipeline, located out of furnace's case.

EFFECT: providing of more complete burning of fuel, increasing of thermal return of furnace, reduction of fuel consumption.
