摘　　要：采用热天平、气相色谱在线联合分析技术（ＴＧ－ ＧＣ） ，对若干种固硫剂的固硫效果，型煤燃烧过程ＳＯ２ 的释放特征进行系统的表征分析和研究。结果表明，由固硫剂和助燃剂复配而成的复合型固硫剂的固硫效率明显优于单组分固硫剂，助燃剂与固硫剂有协同作用。The effect ofcomposition ofsulfur- fixing agents on sulfur-fixing efficien cy and SO2 evolution during combustion of briquettes made from a bituminous coal and an anthracite wasstudied by TG- GC- The resultsshowed thatthe sulfur-fixing efficiency of the complex sulfur-fixing agents prepared by addition ofthe sulfur-fixing and combustion -supporting agents was much higher than that of sulfur - fixing agents alone- Itis also found thatthereis a synergicfunction between the sulfur-fixing and combustion - support ing agents- Theexistenceofthecombustion - supportingagentsincreasesthethermalstab ility ofthe sulfur-fixing product markedly-
