Wet flue gas desulfurization（WFGD） has become the first selection process of flue gas desulfurization in China’s coal fired power plants.While with a lot of applications on WFGD

problems such as fouling

corrosion and insufficient stability of desulfurization system are gradually exposed.This paper researched on current hot topics that use desulfurization additives to improve WFGD system performance

proceeded analysis

classification and evaluation of current desulfurizers from desulfurization agent working mechanisms

comprehensive effects and etc.

and provided basis of choices for desulfurization additives in industrial application.
