  • In order to analyze and compare the desulfurization characteristics of five different kinds of domestic limestons, a thermogravimetric analyzer (TGA) was used in this study. Calcium carbonate contents of the domestic limestone varied from 91 to 96 wt%. Experimental temperature and sulfur dioxide concentration of $850^{\circ}C$ and 2,750 ppm, respectively were selected to simulate commercial operation conditions. In this study, the calcination and desulfurization reaction of limestones were simultaneously occurred and investigated to simulate in-situ desulfurization reaction in commercial circulating fluidized bed combustors. In addition, desulfurization reactivities of limes having the average particle sizes of 37.5, 90.5, 159, 356 and $750{\mu}m$ were investigated. Desulfurization reactivities via simultaneous calcination and desulfurization reactions were 5-20% lower than those of using general desulfurization reactions.
