摘要: 氮氧化物是大气污染的主要因子之一,也是产生PM2.5的诱因之一.NOx主要来源于分解炉内燃料型NOx和回转窑内NOx.通过研究南京市某水泥企业SNCR工程实际运用情况,了解该企业脱硝效果,同时根据NOx排污费征收政策,分析NOx排放浓度与生产成本的关系,为政府控制水泥企业NOx排放工作提出建议.

关键词: SNCR;分解炉;环境管理;成本分析

Abstract: Nitric oxide is (NOx) not only one of the main causes for air pollution,but also one of the incentives to PM2.5 production.NOx is mainly derived from decomposition furnaces and rotary kilns.This paper investigates the practical application of the SNCR project and its effect in denitration in a cement enterprise in Nanjing.The relationship between NOx emission concentration and production cost is also analyzed according to the collection policy of NOx sewage charges.This paper provides useful suggestions for enterprises to implement good environmental protection and efficient production cost control.

Key words: SNCR;decomposition furnace;environmental management;cost analysis
