HEAT TRANSFER OF BODIES PARTIALLY SUBMERGED IN THE FLUIDIZED BED AND ITS INTENSIFICATION

Abstract

The paper deals with the experimental study of the heat transfer bodies enhancement partially submerged in the fluidized bed or floating on its surface by directing heterogeneous jets on the exposed surface of the body (mixture of solid particles with air). Heterogeneous jets were generated directly by the fluidized bed by tubes which placed in the bed and directed to the heat transfer surface. The study shows that the use of heterogeneous jets generated by the fluidizing medium itself, leads to extension of the average surface body area on heat transfer coefficient without altering the energy required on the fluidization process. Reducing the difference in the intensity of the heat transfer process for the body parts which contact with different environments, improves the quality of heat-treatable products.
