摘要分析了水泥窑NOX的形成机理，介绍了分煤、分料、分风等分级燃烧技术的特点。西南某生产线分级燃烧测试结果表明，燃用高硫无烟煤的水泥熟料生产线NOx初始排放浓度高，分级燃烧降低了水泥熟料生产线SNCR脱硝前的NOx浓度，减轻了SNCR的脱硝压力，分级燃烧效率均值在16.38%，分级燃烧后、SNCR前的NOX平均值为1 378.66mg/m³（标）。

关键词: 水泥工业高硫无烟煤 NOx 分级燃烧

Abstract: The formation mechanism of NOx in cement kilns is analyzed, and the characteristics of staged combustion technologies such as coal separation, material separation and air separation are introduced. The results of the staged combustion test of a production line in southwestern China show that the initial NOx emission concentration of the cement clinker production line burning high-sulfur anthracite is high, and the staged combustion reduces the NOx concentration before the SNCR of the cement clinker production line, and reduces the denitration load of the SNCR. The average value of staged combustion is 16.38%, and the average value of NOx before SNCR is 1 378.66 mg/Nm³.

Key words: cement industry high sulfur anthracite NOx staged combustion
