Abstract
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 ℃ 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 µm were investigated. Desulfurization reactivities via simultaneous calcination and desulfurization reactions were 5-20% lower than those of using general desulfurization reactions.
