"Considering simplified equations for estimation of pressure drop in the cyclone/impactor and for gas penetration from FB to the PT-column we tentatively evaluated their possible effects on circulation of solids. Comparison of a theoretical forecast for saturation carrying capacity of gas in pneumatic transport (choking), computed by selected Yang correlation, with the model-computed mass fluxes of solids has indicated possible problems and instabilities of solids flow in some regimes and arrangements, especially with larger orifices, higher height of FB and/or lower gas velocities in PT-column and bigger particles. For control of circulation rate of a given particulate material in the dual FB/PT systems three practically important parameters should be considered: gas velocity in PT-column, cross sectional area of orifice(s) and height of FB."@en .
