Abstract

Abstract: After the uninstalling of gas-gas heater from limestone-gypsum wet desulfurization technology of coal-fired power plants,gypsum rain become serious,and adversely affect the environment.This paper deeply analyzes the sources,forming process and influencing factors of gypsum rain,introduces several common solutions which have certain industrial application value. Combined with the engineering case, the advantages and disadvantages of each solution are discussed,which provide experience for actual WFGD system transformation in coal-fired power plants.Also pointed out it's good for air pollution controlthat the current desulfurization process optimization and develop new wet electrostalic precipitator suited to China's national conditions.

Key words: coal-fired power plants, funnel, gypsum rain, wet flue gas desulfurization, dropletentraiment, gas-ags heater
