Abstract
A mathematical model has been developed to describe the various rate processes occurring in an axisymmetric copper flash-smelting furnace shaft. A particular feature of the model is the incorporation of the four-flux model to describe the radiative heat transfer by combining the absorbing, emitting, and anisotropic scattering phenomena. The model also incorporates the turbulent fluid dynamics of a particle-laden gas jet, chemical reaction kinetics, and heat- mass transfer. The importance of various subprocesses of radiative heat transfer in a flash-smelting furnace has been studied. Model predictions showed that radiation from the furnace walls and between the particles and the surroundings is the dominant mode of heat transfer in a flash-smelting furnace.
