Entrainment from an air fluidized bed of coal particles in a 14.5 cm-ID column has been studied. The effects of gas velocity and mean particle size on the transport disengaging height(TDH) and entrainment rate have been determined The entrainment rate increased with the increase in the fluidizing air velocity but decreased with increase in the mean particle size and the column height above the fluidized bed The date of entrainment rate and the TDH have been correlated in terms of Froude and Archimedes numbers.
