Refuse-derived fuel (RDF)-RDF-5 according to ASTM guidelines-derived from municipal solid waste and other waste materials, has been prepared as a fuel source for power plants in Japan. RDF has been known as a stable and safe solid-fuel. However, some spontaneous ignition incidents occurred during storage of RDF in certain facilities. In the present study, the storage conditions, which might induce the spontaneous ignition in RDF samples, was investigated to understand and prevent this phenomenon. When the initial temperature of RDF sample was consistent, higher water content and shorter induction times was observed (e.g., the induction times of select RDF samples with 5.8% and 16.7% water content, was 446 and 270 min, respectively). Also, the induction time was affected by the size of a RDF sample. No relationship between bacterial fermentation and spontaneous ignition was observed. The linear relationship between the induction time and the inverse of the initial temperature of the RDF sample was obtained in the Arrhenius equation.
垃圾衍生燃料（RDF）-RDF-5 根据 ASTM 指南-源自城市固体废物和其他废物，已被制备为日本发电厂的燃料来源。RDF 一直被认为是一种稳定且安全的固体燃料。然而，在某些设施中储存 RDF 时，发生了一些自发点火事件。在本研究中，研究了可能导致 RDF 样品自发点火的储存条件，以了解和防止这种现象。当 RDF 样品的初始温度相同时，观察到更高的水分含量和更短的诱导时间（例如，含水量分别为 5.8%和 16.7%的选择 RDF 样品的诱导时间分别为 446 和 270 分钟）。此外，诱导时间还受到 RDF 样品尺寸的影响。未观察到细菌发酵与自发点火之间的关系。在阿累尼乌斯方程中获得了诱导时间与 RDF 样品初始温度倒数之间的线性关系。
