Laser Probes of Hazardous Waste Incineration Chemistry: Chlorinated Hydrocarbons

解决了两个阻碍含氯烃焚烧的关键问题：难以检测废气中痕量氯的种类，以及缺乏氯代烃的定量燃烧动力学。一种非侵入性探针，其灵敏度为十亿分之一，将通过首先产生荧光测量来研究。将探索各种紫外线激发和监测波长，以优化灵敏度。第二个问题将通过组装氯化烃燃烧的动力学机制并在100托的甲烷/氯甲烷/氧气火焰中进行测试来解决。所要解决的问题对垃圾焚烧技术具有至关重要的意义。这项研究将导致对燃烧过程中氯化物质命运的机制有更基本的了解，并将加速用于工业源应用的Cl/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.
