摘要

通过对导向管喷动流化床的喷动区和流化区分别进行质量平衡和动量平衡，得出了描述连续流动条件下其床层内粒子停留时间的数学模型。本模型所得计算结果与以前报道的实验结果一致。

Abstract

By using the principles of conservation of mass and momentum in both spout and annular regin

a model was developed for describing the characteristics of particle residence time in a continuous spout-fluid bed with a draft tube.The calculation based on this model agreed with the experimental data reported before.
