    • 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.
    • 为了在煤粉分配器的入口处实现垂直方向的浓度分布的改善,并将粉煤均匀地分配到各自的粉煤燃烧器。 提供了一种粉煤分配器和气体 - 颗粒流量调节装置,其设置在煤粉分配器的上游侧和粉煤管的底部,以将粉煤调节为分支管的浓度,气体 - 颗粒流调节装置 包括沿着粉煤管的基本上整体宽度设置的板状构件,以在俯视图中具有基本上矩形的形状,气体 - 颗粒流量调节装置的前边缘被枢转地安装到粉碎的 煤管,并且可以基于安装到各个分支管的流量传感器的信号自动调整在气体 - 颗粒流量调节装置的上表面和粉煤管的底表面之间形成的角度。
