METHOD TO CONTROL TEMPERATURE OF GASES AT OUTLET OF COMBUSTION CHAMBER OF SWIRLING-TYPE FURNACE AND SWIRLING-TYPE FURNACE Russian patent published in 2013 - IPC F23C5/28 F23N1/00 

FIELD: power engineering.

SUBSTANCE: method to control temperature of gases at the outlet of a combustion chamber of a swirling-type furnace, including facilities for supply of coarsely ground fuel and a flow of finely ground fuel into the combustion chamber, besides, in process of operation they monitor temperature of gases at the outlet of the combustion chamber, flows of fuel are sent with provision of interaction of the burning finely ground fuel flow with the flow of coarsely ground flow. At the same time the ratio of quantity of supplied finely and coarsely ground fuel is varied depending on temperature of gases by increase of relative quantity of supplied coarsely ground fuel as temperature of gases increases at the outlet from the combustion chamber. The range of temperature of gases is maintained within 900°-1150°C.

EFFECT: invention makes it possible to improve efficiency of furnace operation.
