摘　　要：采用 TG-DTA-DTG 热分析联用技术对玉米秸秆在不同升温速率下进行了燃烧实验。考察了着火温度、燃烧速率最大时温度、燃尽温度等燃烧特征参数。根据对不同升温速率下玉米秸秆燃烧过程的分析,用双组分分阶段反应模型能够很好的描述玉米秸秆的燃烧过程。建立了玉米秸秆反应动力学方程,得到了在不同温度区间的燃烧动力学方程和表观活化能、频率因子等燃烧动力学参数,并提出了相应的燃烧机理。The TG-DTA-DTG thermal analysis technology was applied to study on combustion experiments of comstalk in the different heating rate. Combustion characteristics of cornstalk was analyzed according to combustion characteristics parameters, such as ignition temperature, peak temperature at maximum weight loss rate, burnout temperature etc. By analyzed the combustion process of cornstalk in the different heating rate, the bi-component phased reaction model is appropriate to describe the combustion process of cornstalk. A proper combustion mechanism was proposed. The kinetics parameters of cornstalk were obtained according to the experimental data.
