| 摘 要： | 选用北京市大兴区玉米秸为主原料，混配小麦秸、花生壳， 利用热重仪研究混配物料的燃烧特性，并采用Coats-Refern法研究其燃烧动力学特性，为农作物秸秆固体成型与燃烧提供实践与理论数据。研究发现，3试样燃烧都有2个明显的峰值，燃烧过程可分为水分蒸发干燥、挥发分析出及燃烧、固定碳燃烧和燃尽4个基本阶段，在整个燃烧阶段有较大的重叠区域。添加花生壳的混配物料，其燃烧特性及动力学参数受花生壳的影响较大，而添加小麦秸影响较小。

| Abstract: | Taking corn stalks in Beijing Daxing District as the main raw material, and the peanut shells and wheat straw as affixation, the combustion characteristics of mixed materials were studied by using thermogravimetric analysis. The combustion dynamics was analyzed by using Coats-Refern method to offer practical and theoretical data for crop straw combustion. Studies showed that combustion curve of three samples had two distinct peaks, which could be divided into four basic stages: water evaporated to dryness, the combustion of volatiles, fixed carbon combustion and burnout. At the same time, a larger overlapping area was laid in the entire combustion stage. The combustion characteristics and kinetic parameters of mixed materials were influenced by adding peanut shells, and less affected on adding wheat straws. |
