    • A process for producing fuel pellets is described. The pellets are obtainable from a particulate carbon-based material and a binder, the process comprising the following steps: admixing the material and binder, and agglomerating the so-formed mixture by tumbling. The tumbling action, such as in a rotary drum, serves to agglomerate the particles and bind the mixture into the pellets, usually with a variable size distribution. No mechanical compression force is required, and with the binders used, the process can be carried out at ambient temperature. The process provides a simple but efficient process for using waste carbon-based materials, and forming a useable fuel product, which is easily transportable and efficiently combustible. Rotating drum or pan agglomerators are relatively low cost to build, and are capable of very high tonnage throughputs. Customised products can be produced and the process enhances the economics of ash and sulphur removal in coal upgrade plants.
    • 对燃料粒料的制造方法进行说明。 颗粒可以由颗粒状碳基材料和粘合剂获得,该方法包括以下步骤:混合材料和粘合剂,并通过翻滚使所形成的混合物凝聚。 转动作用,例如在旋转鼓中,用于使颗粒附聚并将混合物结合成颗粒,通常具有可变的尺寸分布。 不需要机械压缩力,并且使用粘合剂,该过程可以在环境温度下进行。 该方法提供了使用废碳基材料并形成易于运输和有效燃烧的可用燃料产品的简单而有效的方法。 旋转鼓或盘式聚结器相对较低的建造成本,并且能够非常高的吨位生产量。 可以生产定制的产品,并且该工艺提高了煤炭升级设备中灰分和硫的去除经济性。
