【Abstract】 A mathematical model for calcination, sintering and surface area development of dispersed limestone particle is presented. Calcination process by considering heat transfer, mass transfer of CO 2 through porous CaO layer, and chemical kinetics are described in the model. The diffusion of CO 2 in porous product layer is discussed in more detail. The results of simulation are in agreement with the experimental data.更多还原
