Abstract
To achieve an improvement in concentration distribution in a vertical direction at an inlet of a pulverized coal distributor and uniformly distribute pulverized coal to respective pulverized coal burners. A pulverized coal distributor and a gas-particle flow adjustment device provided on an upstream side of the pulverized coal distributor and at a bottom in a pulverized coal pipe to adjust pulverized coal to branch pipes in concentration are provided, the gas-particle flow adjustment device comprises a plate-shaped member provided along a substantially overall width of the pulverized coal pipe to have a substantially rectangular shape as viewed in plan view, a front edge of the gas-particle flow adjustment device is mounted pivotally to a bottom surface of the pulverized coal pipe, and an angle formed between an upper surface of the gas-particle flow adjustment device and a bottom surface of the pulverized coal pipe can be automatically adjusted on the basis of signals from flow sensors mounted to the respective branch pipes.
