Effect of addition of sulfur fixing agent on sulfur fixation result in coal combustion

For better sulfur fixing result in coal combustion,testing work is made with Ca CO₃ as sulfur fixing agent and Al₂O₃,Fe₂O₃,Na₂CO₃ and C₉H₈Na₂O₄ as fixing aids at varying burning temperature and proportionings of each kind of fixing aids. As evidenced by test result,among the 4 kinds of fixing aids,Na₂CO₃ can produce the most remarkable effect. With Na₂CO₃ as an aid,the sulfur retention rate is up to 63. 64% under low burning temperature and high as 38. 18 under high burning temperature.
