Abstract:

In operation of side A induced draft fan of boiler No.1 in Yaomeng Power Company Limited, the stall phenomenon occurred. According to the operation

data and theory analysis, it was considered that the stall reason of the said induced draft fan is low temperature corrosion caused by ash deposition of the

preheater. After effective measures were adopted, the stall phenomenon was eliminated.

Key words: induced draft fan, stall, low temperature corrosion, ash deposition, responsive measure
