Annotation	Dual separated fluidized beds (FB) or fluidized and transporting bed systems are convenient for cleaning of gases with regeneration of a solid sorbent or for gasification of solid fuels and production of rich fuel gas with practically no content of nitrogen. Our attention was concentrated on development, comparison and checking of three simplified models for solid particle velocity, pressure drop and mass flux in a pneumatic transport reactor (riser). The simplified models have been used in a more general model for flow of solids via orifices between a FB near the incipient fluidization and a tube with vertical pneumatic transport (PT) of solids and circulation back to the FB. The model predictions have been compared with experimental data and validated.
