摘要： 参考垃圾衍生燃料的制备方法考察了市政污泥作为能源的可行性及利用价值，研究了污泥资源化利用前的最佳脱水干化条件及煤粉添加量对污泥燃烧效果的影响. 结果表明，污泥热源干化的最佳时间为4 h，干化后污泥的发热量在18 MJ/kg左右，能量较高，且污泥的发热量随含水率和有机物含量变化而变化. 当干化温度在105~150℃之间时，污泥的可燃有效成分几乎无变化. 污泥含H量较高，燃烧时会有大量挥发分燃烧，这也是污泥燃点低于煤的原因.

Abstract: Experiment was carried out for the resource-oriented utilization of municipal sludge based on the method of RDF (refuse derived fuel). The optimal drying conditions of sludge and the effect of added proportion of pulverized coal on the combustion of sludge were examined. The results showed that the optimal drying time was 4 h and the heating value of dried sludge was about 18 MJ/kg, and the heating value of the sludge was changed with water content and organic content. Besides, the effective ingredients of sludge almost had no change when the drying temperature varied from 105 to 150℃. In addition, the hydrogen content was high in the sludge, so the ignition point of sludge was lower than that of coal.

Key words: sludge derived fuel, refuse derived fuel, resource-oriented utilization, heating value
