AXIAL VOIDAGE PROFILE IN A COLD MODEL CIRCULATING FLUIDIZED BED
The axial voidage profile was measured in a cold model circulating fluidized bed(0.38m in diameter and 9.1m in height)of sand particles as bed materials. Voidage in the riser column increases along the height above the distributor plate with increasing the gas velocity. However, it decreases with an increase in solid circulation rate in the bed. Model correlations to predict the solid circulation rate and the axial voidage profile in the bed are proposed.
