DEVICE FOR ZONED CENTRIFUGAL BURNING USING FLOW OF COMBUSTION AIR Russian patent published in 2018 - IPC F23B40/04 F23L1/00 F23L9/00 

FIELD: power industry.

SUBSTANCE: device for zoned centrifugal burning of fuel contains an upper combustion chamber configured to supply combustion air through it to the combustion chamber and to discharge therefrom a fire column formed during the burning of fuel using combustion air, a lower combustion chamber connected to a lower part of the said upper combustion chamber, the said lower combustion chamber being adapted to supply fuel thereto and with the possibility of supplying fuel therefrom to the combustion chamber ensuring mixing of fuel and combustion air for its ideal burning, an air supply pipe, one end of which is divided into an upper branch of the air supply pipe and a lower branch of the air supply pipe, the said upper branch of the air supply pipe is turned upward, and the lower branch of the air supply pipe is turned downwards with the possibility of supplying combustion air respectively to the upper combustion chamber and the lower combustion chamber, a vortex unit connected to the lower combustion chamber and configured with the possibility to maintain a centrifugal force for the combustion air as the ignition process proceeds in the lower combustion chamber, a fuel supply means formed at a lower end of the vortex unit and comprising a fuel feeder adapted to supply fuel to the lower combustion chamber in a fixed amount and an ash processing chamber located on one side of the said vortex unit and configured to capture and process ash, slag and gas-weighed loose ashes, formed during the burning of fuel.

EFFECT: invention allows to improve the quality of fuel burning, to reduce the emission of harmful substances into the atmosphere and the formation of slag.
