INTENSIFICATION OF SURFACE TO BED HEAT TRANSFER IN A FLUIDIZED BED AT CONTROLLED GAS DISTRIBUTION
Sinopsis
A thermodynamic analysis of fluidized bed behaviour at fluidizing agent redistribution has been carried out. An existence of local fluidization intermediate field at non-uniform gas distribution has been shown. A gas velocity decrease at the same points of the bed has been observed when bodies of different geometry are introduced into the bed. A heat transfer coefficient increase of the body surface to a fluidized bed is obtained if boundary conditions change. A criterion equation which defines maximum heat transfer coefficient values as well as coefficient values before and after the maximum is developed.
