Investigation on heat transfer between gas and rubber particles in fixed bed and vibrated fluidized bed

The effect of parameters on radial heat conductive coefficient is analyzed by researching into the radial heat conductivity of rubber particles in fixed bed. The fluidized bed should be applied to enhance the process of heat transfer between gas and solids in order to minimize the effect of lower heat conductivity of rubber. It is indicated that vibration strengthen rather than gas velocity affects the heat transfer in vibrated fluidized bed (VFB) according to the analysis of the heat transfer correlations. In the case of reaching the same heat transfer results, the VFB can decrease gas velocity more than common fluidized bed can do, and the energy conservation may be realized by using VFB technology.
