摘　　要：针对某厂燃煤锅炉改烧高炉煤气的改造需求,采用Fluent软件进行数值模拟的方法,对高炉煤气旋流燃烧器的流动情况进行研究。研究了不同负荷下燃烧器的温度场和流场分布,讨论了影响燃烧器流动的因素,计算结果通过实验数据验证。此次数值模拟表明改造后的燃烧器符合设计要求,并为运行提供理论依据。According to the demand of a plant transformation coal-fired boiler burning blast furnace gas, the blast fur-nace gas flow on the cyclone burner was numerically studied by means of FLUENT software. The temperature field and flowfield distribution under different load of burner was studied and the influence factors of burner flow was discussed. The re-suits was validated by experimental data. The numerical simulation shows that the modified burners comply with design re-quirements, and provide the theoretical basis for operation.
