Air was used as the carrier gas. Three kinds of glass particles were used as the circulating medium. The effects of gas feed rate, tube-cone clearance, cone angle, particle diameter, and particles loading on the behavior of the semi-cylindrical spouted bed were investigated. The gas velocity in draft tube only depended on the gas feed rate. The gas velocity in the annulus increased with increasing the tube-cone clearance, with increasing the cone angle, with increasing particle diameter, and with decreasing the particles loading. The solids circulation rate increased with increasing the tube-cone clearance. Correlations to describe the annulus gas velocity and solids circulation rate were proposed.}, pages = {107--118}, title = {半円筒形ドラフトチューブ付き噴流層における粒子とガス流の挙動に関する研究}, volume = {33}, year = {1991} }
