摘　　要：随着环保要求的日益严格,电厂燃煤锅炉普遍采用低氮燃烧方式,由此导致水冷壁贴壁处严重缺氧,进而引发了高温腐蚀问题,影响了电厂运行的安全性和经济性。综述高温腐蚀的研究现状,论述高温腐蚀的化学反应机理和影响因素,为进一步炉膛改造提供参考。With the increasingly stringent environment requirements, coal-fired boilers generally use low-nitrogen combustion, which lead to water wall insulation at the serious hypoxia, which lead to high temperature corrosion problems, affecting the safety and economy of power plant operation. The research status of high temperature corrosion is reviewed, and the chemical reaction mechanism and influencing factors are discussed, which provide a reference for further furnace modification.
