EFFECT OF COLUMN DIAMETER ON HYDRODYNAMICS OF THREE-PHASE FLUIDIZATION OF A HOMOGENEOUS TERNARY MIXTURE OF IRREGULAR PARTICLES
A series of experiments have been carried out for homogeneous well-mixed ternary mixtures of five different materials of varying compositions of three different particle sizes in a three-phase fluidized bed.The hydrodynamic characteristics determined include the bed pressure drop, bed fluctuation and bed expansion ratios.The dependence of these quantities on average particle diameter, mass fraction of the fines in the mixture, initial static bed height, material density and diameter of column has been discussed.Based on dimensional and statistical analyses, correlations have been developed with the system parameters, viz., average particle diameter, and initial static bed height, density of solid, column diameter and superficial velocity of the fluidizing medium.Experimental values of bed pressure drop, bed fluctuation and bed expansion ratios have been found to agree well with their respective values calculated by the developed correlations.
