摘　　要：利用热分析仪研究了升温速率等试验参数对城市污泥燃烧特性的影响,并通过改进的Coats-Redfern方法得出污泥燃烧过程中挥发分第一阶段、第二阶段以及焦炭段的最佳机理函数。结果表明:升温速率对污泥燃烧特性影响较大,但水分和粒径整体上对污泥燃烧特性影响不大;数值模拟结果与试验结果具有良好的一致性。The influence of test parameters, such as sewage sludge combustion characteristics were studied by thermal tained best mechanism function of the first volatile combustion combustion stage and the char combustion stage through Coats-R show that, heating rate has greater influence on the sludge combu content of water and the size of particle has little influence on the heating rate, analyzer and on municipal this paper ob- stage, the second edfernmethod. The volatile results stion characteristics, but the whole, the model was fairly agreed with experimental results.
