摘要

分析了某电厂超超临界660MW机组锅炉脱硫系统采用增压风机与引风机二合一运行引起锅炉跳闸

停炉后炉膛负压过低

造成B引风机与电除尘器连接膨胀节变形、撕开等事故。对此

提出了对增压风机、引风机二合一设计的锅炉在调试期间应在低负荷时进行锅炉灭火后炉膛负压变化及引风机自动调节效果的试验

在设计选型时应避免选用特性曲线太陡的风机等建议。

Abstract

The disasters occurred on boilers of ultra-supercritical 660 MW unit after combining the booster air fan and the induced draft fan into one in one power plant

such as leading to boiler trip

too low suction in furnace after boiler shutdown

resulting in deformation and tear of expansion joint connecting the induced draft fan and the electrostatic precipitator

etc.

have been analysed.For these

a test of suction variation in the furnace and effectiveness of automatic regulation for the induced draft fan after outfire of boiler should be carried out during the time of low load in debugging period has been put forward for the designed boiler of combining the booster air fan and the induced draft fan into one

and during the time of type-selection in design

selection of the air fans with too steep characteristic curves should be avoided.
