Measurements are made on the heat-transfer coefficients between particles and fluid in the aggregative fluidized bed. In order to evaluate the heat-transfer coefficients, a proposed model takes into account of the variation of the particles-temperature and the fluid-temperature distributions throughout the bed is developped on the basis of an experimental investigation of the fluidizing behavior. The heat-transfer coefficients obtained by conforming the outlet-air temperature profile to be predicted with the one measured are found to be varied significantly depending on the static bed height, as well as particle diameter and fluid velocity.
