Abstract:

The heat and mass transfer in a bed of iron-ore pellets on a conveyer roasting machine is investigated by mathematical simulation. Two thermal (temperature) waves are observed in the bed, associated with the fluxes of hot gas from the hearth and the heat liberated in magnetite oxidation. By controlling these thermal waves, the filtration rate and temperature may be optimized over the length of the machine, so as to minimize the fuel consumption in pellet roasting and to boost pellet quality. © 2014, Allerton Press, Inc.
