Flame Kinetics and Soot Formation in Chlorinated Hydrocarbon Combustion

法律9634248提议的项目代表了PIıs目前NSF支持的研究的延续。主要研究方向为：(1)研究氯代烃及其与非氯代烃混合物的氧化机理和火焰结构。层流火焰速度的测定将对预混火焰进行，并对非预混火焰的熄灭拉伸率进行测量。随着全面化学反应机理的发展，将评估C/H/Cl比、燃料结构、火焰温度和氯化抑制作用的影响；(2)氯化烃扩散火焰中烟尘形成的研究。这将包括非煤烟和近煤烟火焰的结构量化，确定煤烟开始和熄灭应变速率极限，绘制煤烟剖面图，以评估氯化对煤烟成核、生长和氧化的影响，以及开发C/H/O/Cl体系中煤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.
