摘要
通过对空气预热器预热管壁温度的计算,分析了预热器产生露点腐蚀的原因,并通过增加热空气返回旁路,防止了预热器积灰及露点腐蚀。
By means of temperature calculation of preheat tube wall of air preheater,the reason of dewpoint corrosion occured in preheater is analyzed.The soot and dewpoint corrosion of preheater are prevented by establishing an additional a return bypass.
