An experimental investigation of the characteristic features of mixing of the bottom- and tangentially blown air at different temperatures in a cyclone-fluidized bed chamber with varying operational and geometric parameters has been carried out. Their influence on the temperature fields in the chamber has been established. Optimal values of the pinch diameter, bottom-blown fraction of air, and of the air flow rate that yield the most uniform temperature distribution in the chamber volume are determined.
