摘要

针对烟气脱硫系统不同配置的增压风机系统故障状态

提出了相应的解决措施。对于单增压风机系统增加增压风机事故跳闸触发锅炉总燃料跳闸(MFT)功能

以及增设增压风机旁路系统和增压风机故障快速减负荷(RB)功能

可以避免因增压风机故障跳闸而导致的锅炉MFT;对于双增压风机并联系统设计了2套RB逻辑

保障了机组的安全运行。

Abstract

The effects of cancelling desulfurization bypass duct on booster fan were investigated

and the corresponding countermeasures were put forward

according to the booster fan systems with different configurations.The function of booster fan trip caused boiler master fuel trip(MFT)was added to the single booster fan system

to ensure the unit's safe operation.The bypass and runback(RB)functions of booster fan could avoid boiler MFT caused by booster fan trip

so as to keep the unit running safely.
