摘　　要：针对某公司裂解炉在低氮燃烧器改造后存在的问题开展了分析研究,通过对该裂解炉进行单台燃烧器的CFD数值模拟,以及对温度场、速度场、浓度场的数据分析,找出影响炉膛温度场分布、炉膛压力控制以及NO_(x)排放等达到最佳状态的技术瓶颈,并提出对燃烧器现存结构的改进建议。In this paper,the problems in cracking furnace after low NOX burner modification are analyzed and studied.The single burner CFD numerical simulation of cracking furnace is carried out.Through the analysis of temperature field,velocity field and concentration field,the technical bottlenecks that affect the distribution of furnace temperature field,furnace pressure control and NO_(x) emissions are found out.Some suggestions are put forward for the improvement of burner structure.
