Research of Desulfurization Technology for Dongguang Thermal Power Plant of 2×350 MW Coal-fired Units

According to the operation requirements of Dongguang thermal power plant,and taking the device performance into account,this paper introduces several kinds of desulfurization technology which are commonly used in power plant at present,in China.Firstly limestone-gypsum wet flue gas and ammonia absorption methods for fume desulfuration are elected theoretically.Then the two kinds of desulfurization technology are reviewed realistically.Finally we get the best suitable desulfurization technology for Dongguang thermal power plant.The paper has certain directive significance to Dongguang thermal power plant,and also has good ues for reference of other similar thermal power plant.
