回转式空气预热器漏风探讨

Discussion for Air Leakage of Revolving Air preheater

锅炉回转式空气预热器漏风对锅炉运行经济性和安全性影响较大,实践证明,回转式空气预热器不同部位漏风对锅炉运行的危害不尽相同,但都造成排烟热损耗升高,辅机电耗增大。文章对空气预热器漏风原因及如何整治进行了探讨。

Air leakage of air preheater has considerable influence on economy and reliability of boiler operation,it is proved that different leakage part cause different damage on boiler operation,but it all creates raise of smoke ventilation heat loss and increase of auxiliaries power consumption.The paper makes discussion for air leakage reason and its solution of revolving air preheater.
