| 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.

| Abstract: | The TG-DTA-DTG thermal analysis technology was applied to study on combustion experiments of cornstalk in the different heating rate.Combustion characteristics of cornstalk was analyzed according to combustion characteristics pa- rameters,such as ignition temperature,peak temperature at maximum weight loss rate,burnout temperature etc.By ana- lyzed the combustion process of cornstalk in the different heating rate,the bi-component phased reaction model is approp- riate to describe the combustion process of c... |
