  In order to establish the optimum system of hot return sand cooling in a fluidized bed with a water-cooled pipe, a mathematical model including heat transfer was constructed and numerical calculation was carried out. The present study especially aimed to clarify the effects of inlet sand temperature, water temperature, feed rate of hot sand, coolant air velocity and cooling water on sand cooling behavior. From the calculation, the heat transfer between hot sand and cooling water pipes was found to be the principal process. The control of temperature and feed rate of water is very important for ensuring reasonable sand cooling in addition to the control of convective heat transfer around the cooling pipe.
