The dust was first mixed with NaBH4 powder to adjust the H/Cl ratio. Then, the sample was roasted at low temperature to promote the efficiency of dehalogenation/hydrogenation reaction. By way of Cl- titration, it was found that the roasting temperature (300℃~500℃), roasting time (5 to 25 minutes) and H/Cl ratio (6.0 to 20.0) would change the dissolution of Cl- from 0.0% to 17.5%. After caustic roasting and leaching of the dust, the zinc (17.4 g/l) and lead (1.6 g/l) recovery ratio were found to be 82.7% and 61.8% respectively.

利用NaBH4在低温可促进氯化冶金反应的进行，经由氯离子浓度滴定，发现随著焙烧时间、温度及H/Cl比值之调整，氯离子之溶出量变化亦相对改变，此结果说明在使用NaBH4调配H/Cl比值由6.0~20.0的变化下，烟尘中的氯成分在低温(300℃~500℃)焙烧5~20分钟，可与金属氧化物发生氯化反应，氯离子溶出量显示有0~17.5%不等之变化量。

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。
