抄録

A fluidized bed is utilized in various industrial process such as combustion, drying, mixture, the catalyst reaction and granulation etc In order to achieve the energy saving of the ship, by utilizing the high reactivity of the fluidized bed, and is subjected to heat recovery of the exhaust gas Using the discrete element method in order to grasp the state of the particles for heat recovery and exhaust gas circulating fluidized bed that swings, and to calculate the particle mass flow rate near the wall Through a variety of calculation in different conditions, we have confirmed the effect of swing cycle, angle and the particle diameter has on the mass flow rate
