摘　　要：NO_(x)是大气PM_(2.5)主要形成源之一,水泥生产又是仅次于火电行业的NO_(x)排放源,寻求超低排放技术改造方案是化工治理的关键。本文从建立水泥窑分解炉本征脱硝分级燃烧炉体结构入手,优化水泥窑NO_(x)本征脱降SNCR脱硝分级燃烧技术。实验测试结果表明:SNCR脱硝量相较于SCR分别提升了1.4倍,能有效提升脱硝性能。该研究可以作为炉体优化脱硝改造设计指导原则,以期达到水泥窑超低排放,降低氨水消耗。NO_(x)is one of the main sources of atmospheric PM_(2.5),cement production is second only to the thermal power industry NO_(x) emission source,seeking ultra-low emission technology transformation program is the key to chemical management.This paper starts with the establishment of the structure of cement kiln decomposition furnace,and optimizes the combustion technology of cement kiln NO_(x) intrinsic reduction SNCR denitrification.The experimental results show that the denitrification capacity of SNCR is 1.4 times higher than that of SCR,which can effectively improve the denitrification performance.The research can be used as the guiding principle for the design of furnace optimization denitration modification,in order to achieve ultra-low emission and reduce ammonia consumption of cement kiln.
