通辽热电厂 FM 220.420 风扇磨煤机制粉系统的调试

For Debugging the FM220.420 Type Fan-coal -mill Machine Powdered-system in the Tongliao Power Plant

介绍了通辽热电厂７＃炉（ＮＧ－１３０／３９－Ｍ２）ＦＭ２２０．４２０型风扇磨煤机的结构和性能参数，并在该厂进行了该磨所配的双流道惯性分离器调节挡板的调节特性试验和最大干燥出力试验，找出了该锅炉飞灰和大渣含碳量偏高是煤粉样中含粒径大于１ｍｍ以上的颗粒偏多所致，并分析和讨论了粗煤粉粒子多的原因，提出了相应的改进建议和措施。

Introduce FM220.420model construction and performance parameter of fan-coal-mill of Tongliao power plant 7 # furnace (NG-30/39-M 2),and test the adjustment property and maximum drying ability of double runner inertia separator adjustment stop plate which used this mill in this plant,and find that furnace fly ash and large slag C content was higher,because larger then 1mm coal powder grain diameter were more, analyse and discuss the cause of more larger diameter coal powder ,pilot proper innovate suggestion and step.
