摘要

为实现油料火灾的及时预警，对92#汽油燃烧初期火焰光谱特征进行了实验研究，以探索基于光谱技术的火灾识别和防控。分析了火焰中具有特征谱峰的分子、自由基，说明了其生成机理，发现了火焰特征光谱的分布范围，阐述了不同波段基团光谱强弱的原因，基于基团光谱强度的变化分析了燃烧过程。结果表明，可用于燃烧初期识别的分子、自由基及其特征光谱为C

基512.9，516.5，547.0 nm谱带，CH基431.4 nm谱带，H

O分子927.7，933.3 nm谱带；特征光谱主要位于可见光区和近红外光区，紫外光区较少；处于链引发和传递阶段的基团不易产生积累，光谱强度相对小，处于链反应分支和中断阶段的基团能够积累，光谱强度相对大；分子、自由基的特征光谱强度会随着燃烧的进行而变化，在燃烧达到稳定期后，其独特性消失。

Abstract

In order to realize the timely warning of oil fires

the characteristics of flame spectra in the early stage of 92# gasoline combustion were experimentally studied to explore the identification and prevention of fire based on spectral technology. The molecular and free radicals with characteristic peaks in the flame were analyzed as well as their formation mechanism. The distribution of flame characteristic spectrum was shown

and the reasons for strong and weak spectra of different bands were explained. In addition

the combustion process was analyzed based on the change of spectral intensity of the groups. The results show that molecules and free radicals that are suitable for the recognition of gasoline fire at the initial stage of combustion are C

-512.9

547.0

516.5 nm band

CH-431.4 nm band

O-927.7

933.3 nm band. Spectral characteristics mainly occurred in the visible region and near-infrared region

little in near-ultraviolet region. Group is not easy to accumulate in the initiation and transfer stage of chain reaction

so the according spectral intensity is relatively small. However

some groups are able to accumulate in the chain branch and interrupt stage

thus the spectral intensity is relatively large. The characteristic spectral intensity of molecules and free radicals will change with the combustion process. When combustion reaches the stable stage

its unique characteristics disappear.
