Abstract
The demonstration project transformation with ultra-low emission for environmental protection, which gets the excellent achievement, comes across a series of puzzling problems from the gas system. Because of double factors of re-sistance increase and volume flow rate decrease, the running state points of two induced draft fans move toward the unstable region, causing fan stalls on the low load conditions. Scrambling for air of induced draft fans come cross problems, such as high gas pressure, crack and leakage of bellows expansion joints, inlet baffle migration, and non-automatic operation.Based on analysis of operating points and characteristic curves of induced draft fans,this paper puts forward six solutions, among which replacement of fan impeller is used. By comparison and analysis between historical and present data, provisional mea-sures for solving the problems are put forward.关键词
