摘要
论述了喷动流化床的主要技术进展，讨论了其主要流体动力学特性如喷动气流动形式、床层压降、固体循环速率、最小喷动气速和颗粒停留时间等以及喷动流化床在煤加工方面的应用如裂解、气化和燃烧等．指出了喷动流化床发展前景．
The main technical progresses of the spout-fluidized bed were described. The hydrodynamics of the spout-fluidized bed, such as typical spout shapes, bed pressure drop, solid circulation rate, the minimum spout-fluidizing velocity, particle residence time, were discussed.The applications of the spout-fluidized bed on coal processing, such as pyrolyse, gasification and combustion were introduced. In the end, the future of the spout-fluidized bed were looked into.
