摘　　要：为了提高中储式制粉系统对高水分燃煤的适应性,国电谏壁发电厂通过分析研究,对9号锅炉制粉系统创新性地进行了抽高温炉烟掺混技术改造。改造后采用炉烟风机来抽热炉烟掺混进制粉系统,提高制粉系统干燥出力,降低了制粉电耗,也大幅提高褐煤等劣质煤种掺烧比例,取得较好的经济效益和环保效益,为同类型锅炉改造提供借鉴。To improve the adaptability of Coal Pulverizing Systems with intermediate storage bunker to High moisture coal,Guodian Jianbi Power Plant rebuilt the Coal Pulverizing Systems of No.9 boiler via extracting hot flue gas technology,creatively.After the transformation of the furnace gas fan pumping mixing hot flue gas for coal pulverizing system,Improve the drying capacity of coal pulverizing system,coal Pulverizing reduced power consumption,Also substantially increase such as lignite blending ratio of inferior coal,For the same type boiler to provide reference.
