In the present report, dust collection performances in a fixed bed dust collector and in a cross-current moving-bed dust collector are experimentally investigated. In the experiments, coke is used as a packed medium and fly ash is used as dust. Taking account of the effect of the specific deposit of dust on the collection efficiency, the collection efficiency of a unit layer is expressed by an empirical expression. Simulations of the collection efficiency in the fixed bed dust collector are performed using the empirical expression. In the moving bed, simulations are performed by assuming the shape of the air stream. The results show that the dust collection efficiency is satisfactorily estimated by applying the expression in the fixed-bed and by using the model of the air stream in the moving-bed.
