焦作电厂新厂1号炉制粉系统自1979年2月投产后,一直存在煤粉过粗(R_(90)>25％),出力低、制粉电耗高等问题,严重影响锅炉燃烧的稳定性和经济性。1979年9月开始,将钢球直径由φ60换为φ40,调整了祖粉分离器的进、出口高度,但磨煤机出力和通风量仍未达到设计值。为了解决这些问题,由焦作电厂、电建所、河南中试所、哈尔滨锅炉厂和电力部西安热 Jiaozuo Power Plant No. 1 furnace pulverizing system has been put into operation in February 1979, there has been too coarse pulverized coal (R_ (90)> 25%), low output, high power consumption milling, etc., seriously affect the stability of the boiler combustion Sexual and economic. 1979 September began, the diameter of the ball from φ60 to φ40, adjust the import and export of the progenitor separator height, but the coal mill output and ventilation has not yet reached the design value. In order to solve these problems, by Jiaozuo Power Plant, Electric Power Construction Institute, Henan Pilot Institute, Harbin Boiler Factory and Xi’an Electric Power Department
