Transport Disengaging Height (T. D. H.) was studied theoretically and experimentally for both continuous and batch fluidized beds.
The theoretical elutriation rate of fines above the T. D. H., Vt, was calculated by use of the Maxwell-Bolzmann energy distribution, and it showed good agreement with the experimental value for the continuous fluidized bed.
The theoretical values of the T. D. H., which were defined as Z at V=1.01Vt, coincided fairly well with the present and reported experimental results.
The elutriation height coefficients a were found empirically to increase with increase in particle diameter and with decrease in superficial velocity.
