摘　　要：１引言平焰燃烧器自六十年代问世以来，已广泛使用在各种加热炉上。它具有较多的优点，诸如温度场均匀，压力场均匀，可显著降低炉膛高度等。但平焰燃烧器的供热负荷与加热炉的炉型参数的匹配关系，仍是许多设计人员感到棘手的问题之一［１］，有必要从理论上对其进行研究...On the basis of modifying low Reynolds number k-E model with Richardson number,simulated the velocity field distribution in a model furnace heated by flat-flame burner fromits top, and the affection of alternation of heat charge on the fluid field within the furnace.It was found that the calculated results of the fluid field within the furnace by means ofmodified turbulent model accorded well with measured data. Some valuable research andpractice were operated on the numerical simulation of strong swirl fluid field.
