Research on the Sulfur-Fixing Effect of Compound Sulfur-Fixing Agents from Carbide Slag and Wastes

摘要：

　　In this paper the effects of compound sulfur-fixing agents and compound additives on the sulfur-fixing efficiency were discussed.Therrnogravimetric Analysis was used to study the influence of sulfur-fixing agent and additives on the combustion performance.Besides, X-ray fluorescence was applied to research sulfur-fixing mechanism.The results show that, the best sulfur-fixing efficiency was 78.95%, when the ratio of Ca/S was 2.0, experimental temperature was 1000℃, burning time was 20min, the compound sulfur-fixing agents were 80% carbide slag and 20% wastes, the compound additives were 2% iron additives, 6% aluminum additives, 4% sodium additives, 5% silicon additives.The effects of the four additives on the sulfur-fixing efficiency were Al>Fe>Si>Na.
