马尾松凋落物燃烧烟气成分比较分析

The compare of the components from combust emission of pinus massoniana litterfall

以马尾松凋落的细枝、针叶和树皮为试样,使用热重分析仪-红外光谱分析仪联用(热红联用)技术,分别测定了3种试样在热解和燃烧温度为347、422、497、647℃时的烟气成分。结果表明,马尾松3种凋落物燃烧所产生的气态有机物在种类和排放量上均有较大差异。释放的气体主要成分是CO2、CO、少量的甲醛和一些气态的有机物。在凋落的针叶中CO2的排放量最高,而CO的排放量最低,说明松针是最易燃的凋落物。

Based on thermo gravimetric analyzer-coupled with a Fourier transform infrared spectroscopy （TG-FTIR）,measured the components of the smoke generated by whatever pyrogenation and combustion at 347,422,497 and 647 ℃ of Pinus Massoniana stem,needle and cortex.The result shows that there are obvious differences either in organic gas components or in its concentrations between 3 different litter falls of Pinus Massoniana; the main ingredients have CO2,CO,a small amount of CH4 and some organic substance in gas.The quantities of general and CO2 emission of Pinus Massoniana needle is the highest,while its CO emission is the least,which means the Pinus Massoniana needle is the easiest to burn.
