Abstract
The transport velocity (u tri ) in an inclined fluidized-bed was investigated by varying the bed angle relative to the horizontal plane (0°–90°), the particle diameter (0.021–0.925mm), and density (1,272–4,503 kg/m3). This study employed the emptying time method to determine the transport velocity. The transport velocity for the vertical fluidized- bed (u tr90) was revealed to increase appreciably with the aspect ratio of the fluidized-bed. The transport velocity decreased as the bed angle increased. The ratio of the transport velocity to that for the vertical bed (u tri /u tr90) decreased with an increase in either the bed angle or the ratio of the particle diameter (d p ) to the critical particle diameter (d* p ), i.e., the maximum particle diameter at which the sum of the interparticle adhesion forces had a dominant influence on particle entrainment. Correlations for the transport velocity according to the bed angle relative to the horizontal plane were proposed successfully, based on the experimental data.
