Abstract

An experiment was carried out on heat-transfer and pressure-loss characteristics of a low pressure-loss fluidized-bed heat exchanger with extremely shallow static bed-height of glass beads. The heat exchanger was composed of a staggered tube bank and a multi slit distributor designed specially to reduce the pressure loss. The effects of the shape of the distributor, the mean diameter and static bed-height of glass beads, and the numbers of row of the tube bank on the heat-transfer performance were examined. The heat-transfer and pressure-loss characteristics are compared with existing experimental data, considering the power requirement of blowers and the compactness of heat exchangers.
