The results of this study will help in the development and critical evaluation of models for the thermal destruction of solid organic wastes and will be used in the design and optimization of incinerators. The first part of this study involves the production of polymer particles of optimal properties which can be used for the development and critical evaluation of models of transport processes in the oxidation of the solid compounds. The particles will be produced spherical in shape and monodisperse by atomization of partially polymerized liquid precursors. In the second part of this study, the solid particles will be burned in devices such as an externally heated laminar flow reactor and a thermogravimetric analyzer. Time resolved measurements of the particle properties, gas composition, volatilization periods, and particle temperature will be conducted. The emphasis will be in investigating the temperature-time behavior of the solids under pyrolytic or oxidative atmospheres. By studying well characterized particles the intrinsic kinetics of combustion can be evaluated accurately. The proposed investigation is a fundamental study dealing with the combustion characteristics of plastics and other organic solid hazardous wastes, like adhesives and paints, that end up in the municipal waste streams. This work is based upon the development of polymers synthesized in the laboratory and tailored for the study of individual chemical and physical processes. The polymers will be similar to those used in the plastics industry (Polystyrene, acrylic, highly chlorinated hydrocarbons etc.) both thermoplastics and thermosets, in pure compound form or mixtures thereof.

这项研究的结果将有助于对固体有机废物的热破坏模型的开发和批判性评估，并将用于焚化炉的设计和优化。 这项研究的第一部分涉及最佳特性的聚合物颗粒的产生，这些颗粒可用于开发和关键评估固体化合物氧化中的传输过程模型。 这些颗粒将通过部分聚合液体前体的雾化来产生球形和单分散。 在本研究的第二部分中，将在诸如外部加热层流反应器和热重分析仪等设备中燃烧固体颗粒。 将进行粒子特性，气体成分，挥发周期和颗粒温度的时间分解测量。 重点是研究固体在热解或氧化大气下的温度时间行为。 通过研究表征良好的颗粒，可以准确评估燃烧的固有动力学。 拟议的调查是一项基本研究，涉及塑料和其他有机固体危险废物（如粘合剂和油漆）的燃烧特性，最终在市政废物流中。 这项工作是基于实验室中合成的聚合物的发展，并针对研究单个化学和物理过程进行了量身定制。 这些聚合物将类似于塑料工业（聚苯乙烯，丙烯酸，高度氯化的碳氢化合物等）的热塑料和热塑性，并以纯净的复合形式或其混合物为其。
