分析γ炉膛内相交气流的空气动力学特点得出国外文献中所提出的表征此类炉型的炉内空气动力学效应的准则数M,应作补充修正;按本文提出的准则数K,可以从理论上阐明一些基本事实。所谓火焰形状与可燃混合物喷射速度成自模化的概念,理论上是不妥的,但此种炉型的基本优点是完全肯定 The aerodynamic characteristics of the intersecting gas flow in the γ furnace are analyzed. The number of criteria M proposed in foreign literature to characterize the furnace aerodynamics in this type of furnace is obtained, which should be supplemented and corrected. According to the criterion number K proposed in this paper, From the theoretical elucidation of some basic facts. The so-called concept that the shape of the flame and the jetting speed of the combustible mixture are self-molding is theoretically not suitable, but the basic advantage of such a furnace is that it is completely certain
