Combustion of Chlorinated Hydrocarbons in Hazardous Waste Incineration

拟议项目的目标是从根本上了解氯甲烷和四氯乙烯预混火焰和非预混火焰的动态、热和化学结构，并对火焰稳定、燃料混合和氯代烃焚烧替代品的选择等实际问题提供见解。这项研究将涉及在一定的压力和混合比范围内对逆流燃烧器中的温度、速度和主要物质进行激光测量。详细的结构将与使用现有化学动力学数据的数值预测进行比较，并将使用渐近分析来推导出简化的机理。焚烧是安全处置危险氯化碳氢化合物废物的一种可行技术。然而，这些化学物质比其未加氯的类似物更难燃烧，它们更容易形成烟尘，而且可能会产生微量的剧毒化合物。提出的研究将增加这类化合物燃烧的知识库。

The objectives of the proposed project are to gain fundamental understanding of the dynamic, thermal, and chemical structures of premixed and nonpremixed flames of chloromethane and tetrachloroethylene, and to provide insight into such practical issues as flame stabilization, fuel mixing, and surrogate selection for incineration of chlorinated hydrocarbons. The investigation will involve laser-based measurement of temperature, velocity, and major species in an opposed-flow burner over a range of pressures and mixture ratios. The detailed structure will be compared to numerical predictions using available chemical kinetics data, and asymptotic analysis will be used to derive a reduced mechanism. Incineration is a viable technology for the safe disposal of hazardous chlorinated hydrocarbon wastes. These chemicals, however, are more difficult to burn than their unchlorinated analogs, they form soot more easily, and trace amounts of highly toxic compounds can be generated. The proposed research will increase the knowledge base of the combustion of this class of compounds.
