摘　　要：采用TGDTG-GC技术研究不同固硫剂助燃剂对型煤燃烧性能的影响。结果表明,助燃剂在对煤燃烧产生助燃作用的同时减少甚至消除燃烧反应后期SO2的释放,进一步证实固硫剂与助燃剂的协同作用。同时,有些固硫剂本身也是一种助燃剂,单一组分助燃剂的助燃作用远不如复合型助燃剂,但二者助燃作用均与固硫剂有关。The effect of sulfur-fixing/combustion-supporting agent on combustibility of briquettes was studied by TG/DTG-GC The effect of combustion-supporting agent on sulfur-fixing characteristics is mainly related to reduce or even eliminate the SO 2 evolution in combustion at high temperatures The results further demonstrate the synergic function between sulfur-fixing and combustion-supporting agent Some of sulfur-fixing agent themselves also act as combustion-supporting ones or vice versa The complex combustion-supporting agent are more effective in improving the combustibility than those with single agent The combustion-supporting ability for both agent is also related to the composition of sulfur-fixing agent
