The results show the particle velocity in the annulus area in this equipment is about an order of magnitude higher than that in ordinary spout-fluid beds;
结果表明：稀相喷流床中环隙区颗粒的下降速度比传统喷动床高出一个数量级；
The corresponding static bed height of the biggest spout fluid operating range and the relation between bed pressure drop and spout fluid velocity were determined.
测定了不同物料最大操作区所对应的静床高及喷动流化气速与床层压降、床层空隙率分布的关系。
