摘要：

Transient response of two basic types of fluidized bed heat exchangers, i.e. continuous and semicontinuous ones, to temperature jump disturbances of the feeding agents have been presented. When mathematical exchangers are modelled, a three-phase multi-compartment model of a fluidized bed was used. The model takes into account growth of gas bubbles. Own numerical algorithm was formulated for integration of a set of differential equations appearing as a result of mathematical modelling of the heat exchangers. High efficiency of the method pro sed was shown.
