摘要
为应对"超低排放"新一轮的质量浓度为50 mg/m^3(以φ(O_2)=6%为基准)的NOx排放要求,针对项目中的220 t/h循环流化床锅炉的排放状况进行脱硝改造,选择了SNCR/SCR混合技术,成功实现了NOx质量浓度从300mg/m^3到50 mg/m^3的脱除目标,氨逃逸小于3×10-6(质量分数),取得了很好的应用效果。
To reach the＂ultra clean emissions＂standard of NOx50mg/m^3（6%O2）,the paper analyzes the applications of denox technology by selective non-catalytic reduction（SNCR） adding SCR in 220 t/h circulating fluidized bed boiler.When the initial concentration of NOxof flue gas for 300 mg/m^3 is removal by that of 50 mg/m^3, and the ammonia slip is less than 3×10^-6, emission reduction effect is obvious.
