| With the rapid development of economy in China in recent years,the relatively backward mode of development has brought serious environmental pollution problems,the persistent haze has threatened the people’s health.To this end,the Hebei provincial government requires all coal-fired power generating units must be completed before the end of 2015 to complete the transformation of flue gas pollutant emissions.Datang Baoding thermal power plant,respectively,the reconstruction of low nitrogen combustion,desulfurization system,new system of flue gas denitration,denitration effect as well as the electric transformation projects.These renovation programs checked and accepted by the ultra low emission in early 2016.This article refers to a lot of related ultra-low emissions project literature,analyzes the research present CFB situation of dust removal,desulfurization and denitration system,does basic theory research on technology of ultra-low emissions from coal-fired power plant,and introduces the current mainstream methods and flue gas treatment technology of dust removal,desulfurization and denitration.This paper takes Baoding power plant No.8 and 9 CFB situation ultra-low emission renovation project as the research object,introduces the general situation of the current dust removal system,current situation of desulfurization system and current situation of denitration system in detail,based on the introduction of Baoding power plant,and analyzes the influence factors of ultra-low emission project,discusses retrofit schemes of Baoding power plant No.8 and 9 CFB situation ultra-low emission project,and compares and chooses the suitable scheme,finally analyzes the effect of retrofit scheme and proves the correctness and feasibility of the scheme.The paper enriches the theory research of ultra-low emission project,and has a certain reference significance and guiding role on the promotion of ultra-low emissions project construction. |
