FUEL DISTRIBUTOR FOR FUEL SUPPLY PIPE AND METHOD OF BOILER OPERATION Russian patent published in 2006 - IPC F23K3/02 

FIELD: power engineering.

SUBSTANCE: fuel distributor comprises pipe for supplying fuel that supplies mixed fluid composed of solid fuel and gas to one or more burners arranged over the walls or corner sections defined by the furnace walls, a number of branching pipes originated from the branching section defined inside the pipe for supplying fuel and connected with the burners, and gate mounted inside the pipe for supplying fuel upstream of the branching section. The inclination of the gate with respect to the direction of the flow of the mixed fluid can be changed. The axle of rotation of the gate is mounted at the end section of the gate or at the central part of the gate. The axle is mounted in the central section of the pipe for supplying fuel. The angle of inclination of the gate with respect to the direction of the mixed fluid ranges within ±40°. The distributor is provided with rotating impeller that causes the mixed fluid to flow and is mounted in the pipe for supplying fuel upstream of the gate. The pipe for supplying fuel is mounted for permitting the mixed fluid to flow vertically and is provided with the first pipe for supplying fuel that receives the gate and the second pipe for supplying fuel mounted upstream of the first pipe for supplying fuel and connected with the first pipe. The second pipe is bent in the direction of flow of the mixed fluid. The third pipe for supplying fuel that causes the mixed fluid to flow vertically is connected upstream of the second pipe.

EFFECT: enhanced combustion completeness.
