%X Flow behavior of gas and particles was numerically studied in a bubbling fluidized bed incinerator with tubular distributor.The distributions of instantaneous and time-averaged velocities of gas and particles phases,and particle concentration were obtained.Simulated results show that on the whole particles flowed up in the center,and down near the walls,and an inter-circulation of particles formed.The influences of jetting gas velocity and particle diameter on fluidization were analyzed.Numerical simulations indicate that the optimum spacing between air tubes is in the range of 1.5 to 1.75 in the present study.
