摘　　要：分析了流动加速腐蚀(FAC)现象对火电厂3~#高加换热管束的影响,主要通过研究FAC的腐蚀机理及对火电厂实际运行后高加管束易发生泄漏位置的分析,最终确定管束中Cr含量高于1%时,可将FAC对管束的影响降到最低。This article analyses the influence of FAC to high-pressure heater tubes , by detailed ana- lyses the corrosion mechanism and leaking location of thermal high-pressure heater, finally confirmed if the Cr content is higher than 1%, the risk of FAC is the lowest.

关 键 词：流动加速腐蚀(FAC) 3#高加 CR含量
