Abstract

Abstract: By taking the design of a 130 t/h circulating fluidized bed boiler (CFB) SNCR flue gas denitrification engineering in Shaanxi Yulin as an example, this paper introduces the essential modules in flue gas denitrification, which include the desalted water storage and transportation module, ammonia storage and transportation module, compressed air jet module. Besides, the spray module technological process and the selections of the relevant equipment type and material are described. Also, the selection bases for spray gun and the ammonia analyzer position are introduced. Then, the operation cost of SNCR and SCR is compared. The comparison results indicate that the SNCR technique is more suitable to control the NOx emission for small sized coal fired boiler, especially for flue gas denitrification of CFB boiler.

Key words: circulating fluidized bed boiler, flue gas denitrification, SNCR, ammonia, spray gun, ammonia analyzer
