The development of the semi‐theoretical correlation in Hadzisdmajlovic et al. (1983) for predicting the maximum spoutable height in a spout‐fluid bed, is observed to involve certain discrepancies. Based on their experimental data, a new correlation is proposed. Copyright © 1985 Canadian Society for Chemical Engineering

Pressure drop and flowrate characteristics of a liquid phase spout-fluid bed at the minimum spout-fluid flowrate

The spout-fluid bed is a unique fluid-particle-agitated bed in which spouting and fluidizing occur simultaneously. This technique overcomes such inherent limitations as stratification or slugging in a fluidized bed and restricted flow of annulus solids or instability in a spouted bed. The spout-fluid bed technique gives a much higher rate of circulation and mixing of solids and fluid than any other technique for fluid-particle contact. It allows a larger range of fluid flow rate and good control of spouting or fluidizing. The minimum fluid mass flow rate for maintaining spouting or fluidizing is lower than when the entire bed is only spouted or fluidized. © 1970, American Chemical Society. All rights reserved.
