摘　　要：某发电公司制粉系统采用ZGM113G-Ⅱ(A)型中速磨煤机,一次风经过80℃暖风器加热后,控制热风调门在40%的情况下,磨煤机出口静态分离器挡板角度设定为75°,制粉系统在正常出力(65 t/h)的工况下运行,制粉系统堵管率明显降低,同时也有效保证机组的安全性和经济性.The pulverizing system of a power Co. Ltd. used ZGM113G-Ⅱ(A) medium speed pulverizer. After the primary air was heated by 80 ℃ air heater, the hot air regulating valve was controlled at 40%, and the static separator at the exit of the coal mill was set at 75°. When the pulverizing system operated under the working condition of normal output(65 t/h), the plugging rate of the pulverizing system was obviously reduced, and effectively ensure the safety and economy of the unit.
