热分析广泛应用于燃烧研究的基础和实际研究。煤炭在水泥工业中的高效燃烧非常重要和必要。本研究借助热重分析（TG）和差示扫描量热分析（DSC）研究了三种燃煤添加剂对烟煤和无烟煤燃烧行为的影响。进行了动力学研究并给出了结果。结果表明，燃煤添加剂特别是LSZ可以降低着火温度，提高着火指数Di、燃烧终止指数Df，影响煤样的活化能。燃煤添加剂特别是LSZ可以提高煤的燃烧效率。
Thermal analysis is widely used in combustion research for both fundamental and practical investigations. Efficient combustion of coals in cement industry is very important and necessary. In this research, the effects of three coal-burning additives on burning behaviour of bituminous coal and anthracite were studied with the help of thermogravimetry (TG) and differential scanning calorimetric (DSC) analysis. The kinetic study was carried out and the results were presented. The results showed that the coal-burning additives especially LSZ can reduce the ignition temperature, increase the ignition indexDi, combustion ending indexDfand affect the activation energy of the coal samples studied. The coal-burning additives especially LSZ can improve coal combustion effectiveness.
