降低300MW机组一次风机喘振次数的措施

Measurement of Reducing the Number of Primary Air Fan Surge for 300 MW Unit

国产300MW机组基本上都出现过一次风机喘振现象,情况严重的甚至还出现过因一次风机喘振致使叶片断裂现象。针对珠江发电厂国产300MW机组一次风机多次出现喘振现象,查找出一次风机发生喘振的主要原因,并针对各种原因提出解决方案,为降低国产300MW机组一次风机喘振次数提供了理论依据。

Home 300 MW units all appeared the phenomena of primary air fan surge, even appeared primary air fan surge arousing blade breakage. Aimed at primary air fan of 300 MW unit appearing surge phenomena for many times in Zhujiang power plant unit, found the main reason that causing primary air fan surge, and proposed solving scheme to different reason,supplied theory basis to reduce the number of primary air fan surge of home 300 MW units.
