Description of the temperature, humidity, and concentration distribution in gas-liquid-solid fluidized beds

Abstract

Communication: The computation of the drying kinetics in fluidized bed spraying granulation plants is possible with the models introduced. Starting from mass and energy balances, the models describe the influences of local liquid input, nonideal solid and liquid mixing, heat transport by the solids, and the height-dependent degree of wetness. Conclusions about the existence of an active zone and constant gas temperatures in the central region of the fluidized bed are made.
