湿法烟气脱硫系统运行及发生保护时对机组运行的影响

Influence of Operation and Protection of Wet Flue Gas Desulfurization System on Units

以沙角A电厂5号机组为例,介绍了湿法烟气脱硫(FGD)系统正常运行时增压风机、气-气加热器(GGH)以及旁路挡板的运行方式对机组的影响,结合脱硫系统保护试验,分析了FGD系统发生保护时对机组的影响,对脱硫系统的合理运行提出了参考建议。

Taking Unit 5 in Shajiao A Power Station as an example, this paper describes the influence of booster fan, gas-gas heater（GGH） and bypass damper on the unit during normal operation of the wet flue gas desulfurization（FGD） system. According to the protection test of the FGD system, the effect on the unit is analyzed when the FGD protection occurs. The reference advice is presented about the right operation strategy of wet FGD.
