On the basis of the model concerning agglomerate structure of Ca-based desulphurizer

using ball-plate sintering model

and comprehensively considering the joint effects of volume diffusion and surface diffusion

a new sintering kenetics equation has been established on the basis of agglomerate theory

and the influence of temperature and particle size of the agglomerate upon the sintering of CaO being studied.The sintering process for agglomerate of Ca-based desulphurizer has been simulated by using a computer

at the same time

the variation process of porous structure for CaO particles along with the temperature variation being simulated on the basis of said sintering model

the result of simulation tallies well with the practical situation

proving the said model is feasible.
