摘要
采用热重分析法对市政污泥(污泥SZ)与大同烟煤(煤样DT)及其混合物进行了热解实验研究,揭示了污泥SZ和煤样DT及其混合物热解特性的异同,研究了污泥SZ和煤样DT及污泥SZ的掺比量对两者热解特性的影响,结果表明,市政污泥的挥发分析出特性远好于烟煤;市政污泥和烟煤的热解特性存在显著差异,主要表现在总失重率、失重速率及挥发分析出温度区间等;污泥SZ与煤样DT的掺混对两者的热解过程都有催化作用,而且各自最大催化作用时的掺比量也不相同;市政污泥与烟煤混合物的热解特性与两者的混合比例有关。
Thermogravimetric analysis was used to study pyrolysis characteristics of bituminous coal of datong（coal sample DT）,municipal sludge（sludge SZ） and the mixture.The differences of pyrolysis behavior of sludge SZ,coal sample DT and sludge-coal blends were disclosed,and the influences of sludge SZ,coal sample DT and mixing ratio of sludge and coal on the pyrolysis process were studied.It is found that the pyrolysis feature of municipal sludge is much better than that of bituminous coal; the municipal sludge and bituminous coal have different pyrolysis characteristics parameters in aspects of total weight loss,weight loss rate and volatile release temperature range.Sludge SZ and coal sample DT blending on the pyrolysis process have catalytic effect,and their biggest catalysis of blending specific flow is not the same.The pyrolysis characteristics of sludge-coal blends are related to the mixing ratio of sludge SZ and coal sample DT.
