摘　　要：针对某公司Ⅰ型辐射管在运行过程烟气NO_(x)含量过高的问题,采用数值模拟的方法,建立了辐射管内燃烧过程、换热过程及NO_(x)生成过程数学模型,并根据实际测量数据验证了模型的可靠性。同时对辐射管燃烧筒结构进行优化并对优化后的结构进行了模拟研究,通过原始辐射管结构和改进型结构模拟结果的对比可以看出:通过开设分级供风的方法能有效降低辐射管内的局部高温区,烟气中的NO_(x)含量可降低到100 mg/m^(3)以下,减排效果明显,对实际生产具有指导意义。In order to solve the problem that the NO_(x)content in the flue gas of the type I radiant tube in operation of Steel Company is too high during operation,it firstly adopts numerical simulation method,based on the combustion and NO,model in Fluent,to build the mathematical model under operation of radiant tube.Secondly,the reliability of the model is verified according to the actual measurement parameters.Thirdly,The model is used to improve the structure of the original radiant tube.The results show that the method of opening three times air can effectively reduce the maximum local temperature in the radiation tube,and reduce the NOx content in the flue gas to less than 10Omg/m^(3),which has a significant effect on the practical production.
