In this paper we present a model for determining the performance behavior o
f a CFB reactor. This model is nor sophisticated and does not require compu
ter calculations, but is realistic and convenient for engineers engaged in
the development of new processes. A number of parameters must be evaluated
to use this model. This paper shows what they are; and thus suggests where
future research of CFB should be. Four examples in the different flow regim
es illustrate the use of this model. (C) 2000 Elsevier Science Ltd. All rig
