文章介绍了我公司两台135MW机组烟气脱硫系统运行的工艺流程,阐述了烟气系统、吸收塔系统、再循环系统、静电除尘系统、工艺水等系统的控制策略。目前,我公司火电厂有两台135MW发电机组分别采用FGD石灰石-石膏湿法135MW机组烟气脱硫系统技术进行烟气脱硫,采用两炉两塔方案,将吸收塔设置成逆向喷淋式,在吸收塔的底部道浆池直接
This paper introduces the process flow of two 135MW unit flue gas desulfurization systems in our company, and expounds the control strategy of flue gas system, absorption tower system, recirculation system, electrostatic precipitator system and process water system. At present, two 135MW units in our thermal power plant are respectively flue gas desulfurization using the flue gas desulphurization technology of the FGD limestone-gypsum wet 135MW unit. The two-furnace two-column scheme is adopted and the absorption tower is set as a reverse spraying type. Absorb the bottom of the tower pulp pond directly
