ABSTRACT

The objective of this work was to explore an alternative way to manage the non-biodegradable and non-recyclable fraction of municipal solid waste (MSW) in Vellore city, India. Refuse-derived fuel (RDF) samples with different proportions of plastic, thermocol, foam and jute straw were formulated. The RDF samples were characterized in the form of heating values (proximate and ultimate analysis), surface properties through X-ray diffraction (XRD) and thermal stability through thermogravimetric analysis (TGA). The measured higher heating values (HHV) of four RDF samples varying between 6032 and 6168 kcal/kg were effectively modelled using various empirical models for the prediction of HHV based on their elemental analysis. Higher absolute weight loss in TGA was evident in samples with jute straw while the highest rate of weight loss was noted in samples with a higher proportion of thermocol. Results from this preliminary investigation of RDF samples prepared from non-biodegradable and non-recyclable fractions of MSW warrants an exhaustive analysis of a larger pool of samples to project appropriate RDF composition for better energy recovery.

摘要

这项工作的目的是探索一种替代方法来管理印度韦洛尔市城市固体废物 (MSW) 中不可生物降解和不可回收的部分。配制了不同比例的塑料、热塑性塑料、泡沫和黄麻秸秆的垃圾衍生燃料 (RDF) 样品。RDF 样品的特征在于热值（近似和最终分析）、通过 X 射线衍射 (XRD) 的表面性质和通过热重分析 (TGA) 的热稳定性。使用各种经验模型有效地模拟了在 6032 和 6168 kcal/kg 之间变化的四个 RDF 样品的测量较高热值 (HHV)，以基于其元素分析预测 HHV。黄麻秸秆样品的 TGA 绝对重量损失明显较高，而 Thermocol 比例较高的样品中重量损失率最高。对由 MSW 的不可生物降解和不可回收部分制备的 RDF 样品进行的初步调查结果表明，需要对更大的样品池进行详尽的分析，以预测适当的 RDF 成分以实现更好的能量回收。
