摘　　要：燃煤电厂锅炉的高温腐蚀是发生锅炉爆管事故的原因之一,锅炉高温腐蚀产生的原因较多,分析难度较大。针对张家口电厂7号锅炉发生的再热器腐蚀情况进行分析,并提出针对性的防范措施,为机组的稳定运行起到指导作用。High temperature corrosion on boilers of coal fired power plant is one of the reasons that lead boiler pipe burst. There are many factors that can lead boiler heating surface high temperature corrosion. It is difficult to find out the real one that leads corrosion. This article contains analysis of the reheater corrosion of No. 7 boiler of Zhangjiakou Power Plant ,countermeasures ,and guidance for the running stability of the unit.
