城市污泥和煤混燃特性的热重分析法研究

利用热重分析法对某城市污泥和某煤种及其两者混合物的着火温度、活化能及综合燃烧特性等参数进行了研究。试验结果表明，混合试样和煤相比其活化性能得到了提高，着火温度提前，综合燃烧性能下降。在混燃过程中，煤和城市污泥基本上保持了各自的挥发分析出特性，煤的燃烧表现得更为明显。

A Study of the Characteristics of Mixed Burning of Municipal Sewage Sludge and Coal by a Thermogravimetric Method

A thermogravimetric method is employed to study such parameters as ignition temperature, activation energy and comprehensive combustion characteristics in connection with the burning of municipal sewage sludge and coal as well as their blends. The result of the study indicate that as compared with the case of burning only coal the combustion of blends has resulted in an enhanced activation energy with a lowering of the ignition temperature and a reduction of comprehensive combustion performance. During the blend burning process the municipal sewage sludge and coal have basically maintained their respective devolatilization characteristics with the coal burning exhibiting a more conspicuous behavior in this respect.
