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... 1 Introduction Flat-flame burner since the advent of the 1960s, has been widely used in a variety of heating furnace. It has many advantages, such as uniform temperature field, uniform pressure field, can significantly reduce the furnace height and so on. However, the match between the heating load of a flat-flame burner and the furnace-type furnace parameter is still one of the problems that many designers feel difficult [1], it is necessary to theoretically study it ...
