Comprehensive Solution to Flue Gas Desulfurization and Denitration of Circulating Fluidized Bed Boiler

摘要

With the advantages of high combustion efficiency,wide fuel flexibility and low concentrations of discharged pollutants,circulating fluidized bed( CFB) boiler has been widely used in recent years. However,in order to meet the requirement of new emission standard,it's necessary to add flue gas desulfurization and denitration devices. In this paper,the choice of flue gas purification processes for CFB boiler has been discussed firstly,and then the economy and rationality of the SNCR + CFB-FGD + COA comprehensive solution to flue gas desulfurization and denitration have been analyzed.
