摘　　要：针对外高桥900 MW机组空气预热器漏风率偏高、一次风机静叶开度不能满足机组负荷要求这一影响机组运行的安全性和经济性的问题,依据ALSTOM德国公司提出的改进方案,对该空预器密封系统进行了改造。从检修角度对改造方案进行了剖析。Since the air leakage rate of the air preheaters in Waigaoqiao 900 MW units is too high, and the opening of the primary fan stationary blades can not meet the requirement of the unit loads, a retrofit was carried out for the air preheater sealing system in according to the scheme proposed by ALSTOM Germany. The retrofit scheme is analyzed and summarized in the aspect of maintenance.
