โœฆ Synopsis

Effective thermal conductivities for lateral heat transfer were measured in a fluidizedpacked bed. An analysis of the mechanism of heat transfer was made by comparison with previously determined rates of solids mixing. A general correlation was made of the fluidizedpacked bed thermal diffusivities with the size of the fixed packing and the minimum fluidization velocity in a manner similar to the correlation for lateral solids mixing diffusivities in a fluidized-packed bed.

Although the high heat transfer rates in a fluidized bed are attributed to convective transport by the fluidized particles, no direct comparison has been made between rates of heat transfer and rates of solids mixing. In order

The axial and radial variation of the heat transfer coefficient in a circulating fluidized bed riser column, and the effect of operating parameters thereon, are investigated. The experimental set-up consists of a riser column of 102 mm;102 mm in bed cross-section, 5โ€ข25 m in height with a return leg
