摘要:
 分析杉木林下地表可燃物热解和燃烧烟气成分，对预防森林火灾烟气危害、保障扑火人员的生命安全具有重要的作用。采用热重-红外联用技术对杉木林下的草本、针叶、枝条、球果4种可燃物在氮气、空气、氮气和空气混合3种热解模式下进行烟气成分分析。结果表明，球果、针叶、枝条的热解过程分为3个阶段，草本植物的热解过程分为4个阶段，是否有氧参与对于可燃物的热解具有较大的差异（P＜0.05）。从3种模式下的4种样品红外光谱图中可以发现，每种样品在2 250~2 400 cm-1处的吸光度最高，草本植物的吸光度高于同种模式下的其他3种样品的吸光度。杉木林下可燃物的烟气成分主要有CO2、CO、CH3COOH、H2O、CH4等烃类、醛类、酮类、醇类小分子物质。
Abstract:
 It is important to analyze the pyrolysis of pyrophoric materials and the composition of flue gas in the understory of Chinese fir trees.It plays important roles in preventing the fire hazard of forest fires and ensuring the safety of fire-fighting personnel.In order to understand the smoke composition under Chinese fir combustibles,4 kinds of combustibles,such as herbs,leaves,branches and cones,were analyzed under the 3 modes of nitrogen,air,nitrogen and air.The thermogravimetric experimental results showed that the pyrolysis process of cones and needles,branches could be divided into 3 stages,stage of pyrolysis of herbaceous plants was divided into 4 stages.The presence of oxygen had a great difference in pyrolysis of fuels (P＜0.05).From the infrared spectra of 4 samples in 3 modes,it could be found that the absorbance of each sample was the highest at 2 250-2 400 cm-1,and the absorbance of herb was higher than the absorbance of the other 3 samples in the same mode.The smoke components of the fuel under the Chinese fir combustibles were mainly carbon dioxide,carbon monoxide,acetic acid,water,methane and other hydrocarbons,aldehydes and ketones,alcohols small molecules.
