Abstract

A novel gas fluidized bed heat exchanger with a very small static bed height was developed for a heat exchanging system using a low pressure fan. This fluidized bed is composed of a multislit distributor, a single row of 8 mm diameter tubes, and glass beads 48 MUm to 195 MUm in diameter. The measured performance of heat transfer was excellent and that of fluidization was satisfactory, in spite of the static bed height being as small as 13 mm. In the best case, the test fluidized bed exhibited a heat transfer performance comparable to that of a conventional fluidized bed with a perforated plate distributor and a static bed height of 150 mm, and showed one fourteenth the pressure loss.
