DEVICE TO INCREASE HEAT EMISSION OF FURNACE GAS Russian patent published in 2012 - IPC F24B5/00 

FIELD: power engineering.

SUBSTANCE: device to increase heat emission of furnace gas installed mainly into a domestic furnace between an upper cover of the furnace and its combustion chamber, comprises a screen, preferably the shaped one, where there are windows in the form of slots, preferably in its peripheral zone. The specified windows connect the cavity of the combustion chamber of the furnace with the cavity limited with the upper cover of the furnace, its side walls and the specified screen with the help of horizontally aligned channels, which open into the specified cavity towards each other. There is a swirler installed between the output parts of the channels, and the specified cavity is connected to the stack cavity, the horizontally aligned channels are formed by walls of the furnace and vertically arranged partitions on the screen, the screen is shaped in the form of "V" with arrangement of a shaped rib approximately along the axial vertical line of the furnace.

EFFECT: higher heat emission of furnace gas, more complete burning of fuel, increased duration of furnace operation with unchanged fuel consumption.
