Abstract

Abstract: There were some problems in the operation of YG-75／3.82-M1 circulating fluidized bed boiler in Thermal Power Plant of Heihua Group which included shorter usage period of center cylinder, slag leakage of large air hood, serious wear on boiled upsection of water wall, and etc. Aiming at these problems, the concrete reformation measures were proposed. After the application of the reformation technology in production practice, the stable operation level of the boiler was raised, and favorable economical benefit was obtained.

Key words: circulating fluidized bed boiler, center cylinder, bell jar type air hood, enclosure wall tube
