| Abstract: | SO 2 absorbence with limestone in fluidized bed coal combustion is one technology which has been widely used for a long time. In this paper, a grain model used to simulate the process of calcination and desulfurization reaction of limestone was established on the condition of TGA. The influence of SO\-2 concentration, reaction temperature and particle size were discussed in the model. The calculated results was in good agreement with experimental ones. The established model has significant guidance for desulfurization. |
