通过对几种污泥样品进行热重分析 ,研究污泥的燃烧特性。根据燃烧实验所得的热失重曲线 ,对几种污泥的燃烧过程进行了分析。对实验数据进行处理 ,采用Phadnis法和微分法相结合的方法确定了燃烧反应机理并求出了反应动力学常数A和E。在燃烧的不同阶段 ,总反应速率控制因素不同。
The sludge combustion characteristics were studied by thermogravimetric analysis of several sludge samples. Based on the thermogravimetric curves obtained from the combustion experiments, the combustion process of several sludge was analyzed. The experimental data were processed. Combining the Phadnis method with the differential method, the combustion reaction mechanism was determined and the reaction kinetic constants A and E were obtained. In different stages of combustion, the total reaction rate control factors are different.
