It is revealed that both the roasting and cooling air flow run radially at inlets and then run slantingly upwards or downwards into roasting-preheating zone inside IVAC. And the gas flow in the whole soaking zone is weakened. There are possibly three gas flow patterns in PSF, which are mainly dependent on the ratio of inflow, i.e., the greater the ratio is, the higher the downward roasting air flowrate and the lower the upward air flowrate will be. The critical ratio of inflow mainly depends on the constructional parameters and packed bed conditions of PSF.

结果表明：焙烧风和冷却风在进口处呈放射状，之后斜向上或斜向下分别流入焙烧-预热带和导风墙内；整个均热带内气流较为薄弱；炉内存在三种气流分流的可能，流入风量比是决定气流分流的最主要因素，其中，流入风量比增加，焙烧风下行趋势增大，而冷却风上行趋势减小；临界流入风量比主要取决于结构参数和料层情况。
