Abstract

The heat transfer coefficient between a granular bed with aeration and a moving heating tube submerged in the bed was measured by use of a heat flux generator developed specifically for rapid measurement. The velocity of air flow was limited to less than the minimum fluidization velocity. A heat transfer model taking account of the effect of air flow was proposed. It was confirmed that this model can describe the effects on the heat transfer coefficient of various operation parameters including the velocity of air flow, the thermal properties of granular material, particle diameter and shape, and the diameter of the heating tube.
