摘　　要：燃烧中固硫是一种适合我国国情的燃煤脱硫技术。本文探讨了燃煤高温固硫过程的主要反应机理和一些常用固硫添加剂的助固硫作用,分析了影响固硫效率的主要因素,进而提出实际应用中应考虑的提高固硫效率的措施。The technique of sulfur retention during coal combustion is a kind of sulfur capture technique conforming to the national conditions of China. The principal reaction mechanisms of the process of this technique and the sulfur retention -assisting effect of several common additives are discussed. The main affecting factors of sulfur retention efficiency are analysed, and then the countermeasures that should be considered in practical application are proposed.
