Laser Probes of Hazardous Waste Incineration Chemistry: Chlorinated Hydrocarbons

解决了阻碍含氯碳氢化合物焚烧的两个关键问题：难以检测废气中的微量氯物种，以及氯代烃缺乏定量燃烧动力学。将通过首先产生荧光测量来研究具有十亿分之一灵敏度的非侵入性探头。将探索各种紫外光激发和监测波长，以优化灵敏度。第二个问题将通过组装氯代烃燃烧的动力学机制并在100托的甲烷/甲基氯/氧火焰中进行测试来解决。被攻击的问题对垃圾焚烧技术至关重要。这项研究将导致对燃烧过程中氯化物质去向的机制有一个更基本的了解，并将加速工业污染源应用的氯/HCl监测仪的开发。

Two key issues hindering the incineration of chlorine containing hydrocarbons are addressed: the difficulty of detecting trace chlorine species in exhaust streams, and the lack of quantitative combustion kinetics for chlorinated hydrocarbons. A nonintrusive probe with fractional part per billion sensitivity will be studied by first producing fluorescence measurements. Various uv excitation and monitoring wavelengths will be explored to optimize the sensivity. The second issue will be addressed by assembling a kinetics mechanism for chlorinated hydrocarbon combustion and testing it in a methane/methyl chloride/oxygen flame at 100 torr. The problems being attacked are of critical importance to waste incineration technology. The research will lead to a more fundamental understanding of the mechanisms responsible for the fate of chlorinated species during combustion, and will hasten the development of a Cl/HCl monitor for industrial source applications.
