采用差示扫描量热法（DSC）对不同粒级的原煤和精煤进行了燃烧特性和动力学分析。三种煤样（索马、Tuncbilek和Afsin Elbistan）的DSC曲线显示两个反应区。第一反应区是由于水分损失（吸热），并且在环境温度至150 ℃的温度范围内观察到。第二个区域是由于燃烧而产生的放热区域，在150 - 600 ℃的温度范围内观察到。用Roger和Morris动力学模型测定了样品的动力学参数，并对结果进行了讨论。
In this research, differential scanning calorimetry (DSC) was used to determine the combustion behavior and kinetic analysis of raw and cleaned coal samples of different size fractions. DSC curves of the three coal samples (Soma, Tuncbilek and Afsin Elbistan) showed two reaction regions. The first reaction region was due to moisture loss (endothermic) and observed in the temperature range of ambient to 150C. The second region was the exothermic region due to the combustion and observed in the temperature range of 150 to 600C. Kinetic parameters of the samples were determined using Roger and Morris kinetic model and the results are discussed.
