Theoretical modeling of simultaneous processes of coke burning and limestone decomposition in a furnace

A one-dimensional mathematical model is presented for a combined process of limestone calcination and coke burning in a reactor with allowance for kinetics of physical and chemical transformations. The model makes it possible to obtain the distributions of the gas-phase composition, temperatures of the solid and gas phases, and mass flow along the furnace as functions of the intensity of air, raw materials, and fuel supply into the furnace, their initial temperature, and the size of coke and limestone particles.
