摘　　要：根据NOx产生和分解的化学反应动力学方程式，建立了单角煤粉炉中NOx生成模型。引用已有的单角炉中两种燃烧器后温度和氧气浓度的实测结果，计算了回流区中的NOx浓度分布。分析了3种燃烧器的NOx生成特性，讨论了煤粉浓缩到NOx生成的影响。A model of NOx formation was established for a single pulverized coal furnace according to the chemical reaction dynamic equation of formation and decomposition of NOx The NO. distribution in the recirculation zone was calculated using the existing measured temperature and O2 concentration behind two types of burner inside a single pulverized coal furnace. Properties of NOx formation were analyzed for three types of burner and effect of enriched pulverized coal to NO. were discussed.
