Abstract
According to the agglomerate sintering model of Ca-based sorbents,the sintering kenetics equation for the agglomerate particles was deduced.In these equations,the mechanisms of volume diffusion and surface diffusion are considered comprehensively,and the feasibility of the agglomerate sintering model is verified by using computer simulation.Moreover,based on the model,the temperature effect on porosity during the sintering process was simulated by the mathematical method,and the model was verified through the BJ-2 thermal balance.
