摘要
对于Ｇｅｌｄａｒｔ－Ｄ类颗粒在负压差漏斗－立管系统的悬料操作区的压降可以通过郭慕孙提出的气固移动床的公式求得。计算所得的压降大小与实验结果相比较误差在２０％的范围内；并且证明悬料区的总压降可以近似等于立管的压降。
The experiments shows that the pressure drop of hung-up regime in hopper-standpipe system for coarse particles can be estimated by using the equation presented by Kwauk[4] which is usually used for moving-bed, and the error is within the range of ±20%. The total pressure drop in hung-up regime is approximately equal to that in the standpipe.
