Mathematical Model of Limestone Calcining in the Shaft Furnace

The article reviews the operation principle of the shaft furnace for calcination of carbonate materials and the options for description of thermophysical processes occurring in these furnaces. It provides equations of heat transfer by radiation and convection, special features of thermal interaction between the gas flow and surfaceof solid particles, influence of thermophysical properties and content of particles on efficiency of furnace performance as well as the possible chemistry of reactions to lime dissociation parameters. Keywords: dissociation of carbonate materials, thermophysical processes, radiation, convection, dissociation chemistry
