抄録

Heat transfer characteristics were investigated in an 80-mm ID jetting fluidized bed with a conical distributor and center nozzle using 0.262-mm alumina particles as the bed material. The temperature profiles at different nozzle diameters, different nozzle gas velocities and temperatures were measured by means of very thin thermocouples. Analysis of experimental data suggests that the axial temperature profiles mainly depend on the nozzle gas momentum. The axial temperature dissipation rate is related to Froude number and the nozzle number. Transverse temperature profiles can be represented by an empirical correlation including the nozzle number and the ratio of radius to nozzle diameter. The thermal penetration height and the thermal boundary were also discussed.
