摘　　要：某火电厂无GGH湿法脱硫机组运行中出现的烟囱降雨现象,分析影响"湿烟囱"降雨的因素,找出该电厂无GGH湿法脱硫机组烟囱降雨的主要原因。从湿法脱硫系统的设计和运行等方面提出解决问题的方法和建议,通过分析认为,完善除雾器设备,保证电除尘高效运行,可以使烟囱降雨现象有所缓解。This paper introduces the phenomenon of stack ＂rainout＂ in the wet flue gas desulphurization system for the thermal power plant units without GGH,analyzes the factors affecting ＂rainout＂ of wet stack and finds out the main causes resulting in stack ＂rainout＂ of wet flue gas desulphurization for Wangtan Power Plant without GGH.Some measures and suggestions are put forward based on design and operation.Also it is analyzed that perfecting the mist eliminator equipment and ensuring the efficient operation of electrostatic precipitator may relieve the phenomenon of stack ＂rainout＂.
