Abstract Based on "low NOX burner + staged combustion +SNCR", through source control, post-emission management, whole system intelligent process control, whole process refined operation control and other measures, the cement clinker production line denitrification transformation was carried out. After modification, the nitrogen oxide emission concentration is less than 50mg/m3, ammonia slip is less than 8mg/m3, ammonia consumption is about 0.85m3/h, and the clinker ammonia consumption is 3.96kg/t.clinker, achieving the purpose of energy saving and consumption reduction and ultra-low NOX emission.
