摘　　要：论述了快速床区流体动力学的结构，研究了快速床区纵向和横向悬浮密度分布的规律及相应的计算公式。对影响快速床区动力学结构的主要因素，如固体颗粒的循环率、气体速度等进行了试验研究，对循环流化床锅炉的设计和运行有一定的指导意义。The hydrodynamic structure of fast bed is discussed in this paper. Distribu- tion regularity and corresponding calculation formula of suspension density at vertical and horizontal direction in the fast bed region were studied. Themain influence factor of hydrody- namic structure in the fast bed region , such ascirculating rate of solid particles , gases veloci- ty etc. are discussed. The result have a certain guiding significant for design and operation of circulatingfluiized bed boiler.
