摘　　要：采用CFD数值模拟方法对采用分段加热技术焦炉燃烧室的温度分布及NOx浓度场进行研究，分析分段加热技术的应用效果，以及不同空气分配比例对NOx生成的影响。模拟结果表明在采用焦炉煤气加热条件下，空气分段加热技术能有效提高燃烧室高向温度分布均匀性、降低NOx的生成量，并且一段空气比控制在65％最为合适。The temperature profile and concentration field of coke oven combustor was researched using the method of CFD numerical simulation, in order to get the application of staged combustion with different fuels and the effect of the air distribution ratio on the NOx formation. The results show that the air staged combustion with COG as the fuel can effectively improve the temperature distribution in the height direction of the eombustor and reduce the NOx production, and that the most suitable primary air distribution ratio is 65%.
