Flow characteristics of a spouted bed with a porous draft tube have been investigated experimentally. In this study, both a cylindrical tube and a conical-cylindrical tube were used as the draft tube. As a result, the efficiency of gas-solid contact and solids circulation rate in the bed were considerably improved by inserting a conical-cylindrical porous draft tube into the bed. Moreover, it was confirmed that the gas flow rate through the annulus reached nearly the level of a conventional spouted bed by using conical-cylindrical porous draft tube.
