Pressure drop across a perforated-plate distributor in a gas-fluidized bed

Abstract

Pressure drops across a perforated-plate distributor, with and without a bed present, were investigated and a disagreement was found. A “real minimum uniform fluidization velocity”, Urmufi was defined at which the distributor pressure drop was consistent with that in an empty bed. An approach for modifying the orifice equation when the gas velocity was smaller than t/rmuf was proposed. © 1991, The Society of Chemical Engineers, Japan. All rights reserved.
