Flame Kinetics and Soot Formation in Chlorinated Hydrocarbon Combustion

摘要法律9634248建议的计划代表了PiıS目前由美国国家科学基金会资助的研究的继续。拟开展的工作主要集中在：(1)C2-氯代烃及其与非氯代烃混合物的氧化机理和火焰结构的研究。对预混火焰进行层流火焰速度测定，对非预混火焰进行熄火伸长率测定。随着综合化学反应机理的发展，将评估碳/氢/氯比、燃料结构、火焰温度和氯化抑制的影响；(2)氯代烃扩散火焰中碳烟形成的研究。这将包括量化非碳烟火焰和接近碳烟火焰的结构，确定碳烟起始和消光应变速率极限，绘制碳烟分布图，以评估氯化对碳烟成核、生长和氧化的影响，以及开发C/H/O/Cl系统中碳烟形成的详细动力学模型。后一项任务代表了PI的一个新的研究领域。

Abstract Law 9634248 The proposed program represents a continuation of the PIıs present NSF supported research. The major focuses of the proposed effort are: (1) The study of the oxidation mechanisms and flame structure of C2-chlorinated hydrocarbons and their mixtures with non-chlorinated hydrocarbons. Laminar flame speed determinations will be made on the premixed flames, and extinction stretch rates measured for the nonpremixed flames. The effects of C/H/Cl ratio, fuel structure, flame temperature, and inhibition due to chlorination will be assessed along with the development of a comprehensive chemical reaction mechanism; (2) The study of soot formation in chlorinated hydrocarbon diffusion flames. This will include the quantification of the structure of non-sooting and near sooting flames, the determination of the soot inception and extinction strain-rate limits, the mapping of the soot profile in order to assess the effects of chlorination on soot nucleation, growth and oxidation, and the development of detailed kinetic models of soot formation in C/H/O/Cl systems. This latter task represents a new area of research for the PI.
