%X Ca(OH)_2 and CaCO_3 were selected as the main sulfur-fixed agent, their mass ratio is 2:3. Ver-miculite and Na_2CO_3 were selected as the additives. The influence on the desulphurization ratio by the addition of main sulfur-fixed agent and additives were studied under Ca/S = 2. 25. Result shows that the desulphurization ratio of powder coal with the addition of sulfur - fixed agent can achieve 85% at 950℃ and burning half an hour. TG experiment was carried on the coal with different sulfur-fixed agents, their effects on the coal combustion characteristic and kinetic parameters were analyzed. Conclusion draws that the addition of main sulfur-fixed agent and additives not only enhanced the desulphurization ratio, but also promoted coal combustion and reduced the a-mount of coal ash.
