关键词: 梯度燃烧超低排放 NOx

Abstract: In a 3 000t/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 50mg/Nm³. The emission indicators meet the regional environmental protection emission requirements, and the modification effect is significant.

Key words: gradient combustion ultra-low emission NOx
