Elutriation rate coefficient k'' was experimentally studied for the spouted bed (θ=60°) and the fluidized bed. The effects of various particles and operating conditions on elutriation were examined and an empirical correlated equation was obtained with a deviation within ±20%. It was found that the elutriation of fines was closely related to the length of particles bed L. The difference of elutriation rate coefficient k'' in this work and k proposed by Hercules et al.4) was investigated by considering the particles concentration distribution in bed, and it was recognized that k'' was better than k, considering the mechanism of the elutriation rate.
