摘要

It is established that the hydrodynamics of a pseudo-fluidized bed (PB), and consequently the temperaturernand concentration fields in a PB, are mainly determined by the hydrodynamics of the whole chemicalrntechnology system (CTS) within which a PB functions.rnIt is noted that a PB within the composition of some technological device is a sub-system of the whole CTSrnand therefore it is subject to its system properties that are determined by a quantitative, functionalrndependence of actual PB scales of a hydrodynamic nature on primary parameters of the PB itself and onrnprimary hydrodynamic parameters of the whole PB.rnTransfer of quantitative information about PB hydrodynamics, and consequently about temperature andrnconcentration fields within a bed from one piece of equipment to another is almost impossible due to thernabundance of similarity criteria and the small number of degrees of freedom for providing theirrnsimultaneous equality.rnAn algorithm is proposed for selecting commercial PB equipment in combination with a CTS.
