摘　　要：目前国内加热炉NOx排放难以满足最新规定要求,控制和治理加热炉烟气NOx污染的技术研究和应用已经迫在眉睫。可以从炉内燃烧过程中以及燃烧过程后两个不同环节着手,采取相应的技术措施实现对NOx生成进行控制。加热炉烟气脱硝技术的选择应根据炉型、炉况、燃烧形式、排烟形式及NOx排放指标等因素来综合选定。At present,the NOxemission of domestic heating furnace is difficult to meet the latest requirements,so the research and application of some technologies to control and treat the NOxpollution of heating furnace flue gas are imminent.The corresponding technical measures can be taken to control the generation of NOxfrom the two different links during and after the combustion process in the furnace.The selection of flue gas denitration technology of the heating furnace should be based on the furnace type,furnace condition,combustion form,smoke exhaust form,NOxemission index and other factors.

关 键 词：加热炉 烟气 脱硝 NOx控制技术
