PULVERISED COAL-GAS FLOW DISTRIBUTOR Russian patent published in 2012 - IPC F16K11/10 F23K3/02 

FIELD: power industry.

SUBSTANCE: pulverised coal-gas flow distributor includes inlet branch pipe, housing having end cover at the top, in a circumferential direction of which outlet branch pipes, convergent-divergent constriction arranged in housing between inlet and outlet branch pipes are arranged. Partitions are arranged under cover of housing between inlet cross sections of each tap and internal part of housing. Those partitions are made in lower part or completely rotating. Turning parts of partitions are made so that circles described with their lower edges during rotation cross the housing axis at the distance from flow passage of constriction, which is equal to H=(0.6-1.5)R*tgα,where α - inclination angle of inlet confuser of constriction, and R - minimum distance from edge of flow passage of constriction to the housing axis.

EFFECT: improving reliability, economy and ecological cleanness of thermal power plant due to providing high and adjustable uniformity of distribution of fine pulverised coal.
