Abstract
A hydrodynamic study of conical spouted beds equipped with draft tube has been carried out for Geldart group D particles. Based on a design of experiments, the performance of conical spouted beds provided with draft tube has been studied by measuring different hydrodynamic parameters (minimum spouting velocity, operation pressure drop, solid circulation rate) and the influence of the geometric factors of conical contactors and draft tubes (open-sided draft tubes), and particle properties on these hydrodynamic parameters. The results show that the factors studied (bed height, angle, inlet diameter, width of the draft tube faces, particle diameter) have great influence on the hydrodynamic parameters.
