Taking the Yiyang Power Generation Co., Ltd. two stage of 2×600 MW supercritical coal pulverizing system of once through boiler unit as the object of study, the causes of the unsmooth coal drop from coal bunker under positive pressure of coal pulverizing system and the direct impact on safe and economic operation of boiler were analyzed. According to the field conditions and the usual solutions ofcoal bunker block in coal-fired thermal power plant, the actual solutions were proposed: improving the streamline of coal bunker, "relatively shortening" the fall height of raw coal, loosening piecewise, reducing the coal level regularly, putting the inlet of the bunker as middle aspossible, enhancing fuel management and standardizing operation and so on.
