Research and Application of New Wet Desulfurization Efficiency Improvement Technology in the Implementation of Ultra Low Temperature Transformation in Thermal Power Plants
According to the"14th Five Year Plan"for ultra-low emission transformation of coal-fired power generation enterprises in Yunnan Province,Yunnan Energy Investment Weixin Energy Co.,Ltd.(hereinafter referred to as"Weixin Power Plant")is required to carry out ultra-low transformation of Unit 1 and Unit 2 in 2023 and 2024,respectively,to meet the requirements of no more than 10,35,and 50mg/Nm3 for particulate matter,sulfur dioxide,and nitrogen oxides.After research and demonstration,the technical route for improving the efficiency of the existing limestone gypsum wet flue gas desulfurization system has been ultimately determined.This article systematically proposes how to use this route to solve the problems of low desulfurization efficiency and low defogging efficiency in limestone gypsum wet flue gas desulfurization devices.
