摘　　要：为提高煤炭燃中固硫效果,以Ca CO3作为固硫剂,分别以Al2O3、Fe2O3、Na2CO3、C9H8Na2O4作为固硫助剂,探索不同燃烧温度下不同固硫助剂及其用量对固硫效果的影响。试验结果表明:四种固硫助剂中Na2CO3对煤炭燃中固硫效果的促进作用最明显,以其作为固硫助剂时,低温条件下的固硫率高达63.64%,高温条件下的固硫率可达38.18%。For better sulfur fixing result in coal combustion,testing work is made with Ca CO3 as sulfur fixing agent and Al2O3,Fe2O3,Na2CO3 and C9H8Na2O4as 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.
