Causes Analysis and Counter-measure on Damage of 1000MW Unit Booster Fan

Chen Min-shen

Abstract

The booster fan of 1000 MW unit occurs blade damage during operation.The direct cause of blade damage is vibration of internal rib plate which lead to fatigue fracture,and the booster fan operates within unstable area are the main reason of vibration.By changing blade installation angles,improving resistance of flue gas system and the fan supporting rigid measures,which effectively solved the vibration of booster fan and avoid similar phenomenon.
