Abstract: For coal powder in southwest, sulfur fixing technology of coal powder combustion in this paper has been studied by thermodynamics calculation and experiment. Results show that, The efficiency of sulfur fixing of CaO in experiment is highest; when n(CaO)/n(S) ratio equal to 2.0, additive MnO2 enhances the efficiency of sulfur-fixing of fixing reagent CaO. MnO2 is easier to decompounds gradually to Mn2O3 and Mn3O4. one side the oxides of manganese can catalyze the reaction of sulfur-fixing , on the other hand Mn3O4 can absorbs SO2 to turn to MnSO4.
