Show adverse public opinion regarding this disposal technique has precipitated a strong effort to more optimally design incinerators. It is essential to understand the fundamental thermal destruction behavior of a wide range of organic hazardous wastes in order to more efficiently design incinerators. Development of this knowledge is complex since the environment in an actual incinerator consists of a number of different chemical and fluid dynamic regimes [4]. In each of these regions, the conversion of organic wastes into their products is controlled by different fundamental mechanisms. It is the understanding of these mechanisms that is essential for the proper modelling, design, operation and regulation of an incinerator. Globally, the incineration process involves the conversion of the organic waste material. Throughout this complex process, there are a number of stable intermediates generated and then converted to final products. Generally, this conversion results in less hazardous products. However, many of the stable intermediates which are generated are themselves hazardous materials. The USEPA has designated any remaining hazardous intermediates to be Products of Incomplete Combustion (PICs) should they exit the incinerator. A fundamental understanding of the mechanisms which results in both the generation and consumption of these candidate PICs is also essential for modelling, design, operation and regulation of an incinerator. The thrust of this paper will be to present some recent results regarding the fundamental combustion characteristics of dichloromethane (CH CI ). The chlorinated methanes (CH CI, CH2C12> CHC1 CC14) represent a subset of the general class of hazardous wastes termed the chlorinated hydrocarbons. 5.3.2 |
