ABSTRACT

A film model of heat exchange of a disperse medium with a macrosurface under the conditions of ascending motion of a gas is suggested. A model equation is obtained which yields the dependence of the heat-transfer coefficient on determining factors. It is used to correlate experimental data in different systems: fluidized bed, circulating fluidized bed, and vertical pneumatic transport.
