摘　　要：河北省邢台市某3 000t/d水泥生产线,通过分解炉系统改造和SNCR系统优化,使分解炉扩容60%,提高了氨水利用率,实现了烟气NOx排放浓度<50mg/Nm^(3)的排放指标,满足了地区环保排放要求,改造效果显著。In a 3000 t/d cement production line in Xingtai City,Hebei Province,through the modification of the calciner system and the optimization of the SNCR system,the calciner volume was expanded by 60%,the ammonia utilization rate was increased,and the flue gas NOx emission concentration was lower than 50 mg/Nm^(3).The emission indicators meet the regional environmental protection emission requirements,and the modification effect is significant.

关 键 词：梯度燃烧 超低排放 NOx
