摘　　要：由于循环流化床锅炉拥有分段燃烧和低温燃烧特点,为保证其氮氧化物排放达标,SNCR脱硝技术近年来开始大量在循环流化床锅炉上应用。基于此,文章将简单分析氮氧化物生成机理及控制手段,并结合陕西陕焦化工有限公司锅炉能效升级脱硝优化应用实践,探讨SNCR脱硝技术在循环流化床锅炉上的应用及优化。Because the circulating fluidized bed boiler has the characteristics of staged combustion and low-temperature combustion,in order to ensure that its nitrogen oxide emission meets the standard,SNCR denitrif ication technology has begun to be widely used in circulating fluidized bed boilers in recent years.Based on this,this article will briefly analyze the formation mechanism and control methods of nitrogen oxides,and combine the boiler energy eff iciency upgrade denitration optimization application practice of Shaanxi Shanjiao Chemical Co.,Ltd.,and discuss the optimized application of SNCR denitrif ication technology in circulating fluidized bed boilers.
