Characterization and pelletization of refused derived fuel (RDF)

ICC集团正在开发一种基于气化技术的废物转化为能源的过程。城市固体废物在材料回收设施（MRF）接收，在那里废物的不可燃部分被清除。其余77%的材料含水率为24%。物料用电厂的废热烘干至15%。松散和粉碎的物料不能用于现有的上升气流气化炉。原料应制成球团或压块。浓缩后的原料的固定碳含量为8.8%，对于气化工艺来说是很低的。因此，需要将致密燃料与废木材混合，以将固定碳含量提高到至少15%。目的是测试拒绝衍生燃料（RDF），并研究从这些残留物中制造耐用颗粒所涉及的参数。ICC集团还需要确定颗粒的物理和组成特性，以及批内和批间的可重复性。因此，UBC将使用不同的混合配方，对材料进行预处理以及添加粘合剂进行一系列的制粒试验。然后将对生产的颗粒进行热值、化学成分、氯含量和灰分含量的测试。然后对生产的颗粒进行耐久性和硬度测试。ICC集团和ubc之间的初步合作研究和开发旨在建立长期的研究伙伴关系，以优化从拒绝衍生燃料（RDF）生产耐用颗粒的整个连续工艺线。

ICC Group is developing a waste to energy process based on gasification technology. The Municipal SolidWaste is received at the Material Recovery Facility (MRF), where the non-combustible portion of the waste isremoved. The remaining 77% of the material has 24% moisture content. The material is dried with waste heatfrom the power plant to 15%. The loose and shredded material can't be used in the existing updraft gasifier.The feed stock should be pelletized or briquetted. The fixed carbon content of the feedstock after densifying is8.8% which is very low for the gasification process. Thus, it's needed to mix the densified fuel with wastewood to increase the fixed carbon content to at least 15%. The objective is to test the Refused Derived Fuel(RDF) and to investigate parameters involved in making durable pellets from these residues. ICC Group is alsoin need of determining the physical and compositional characteristics of the pellets, as well as in-batch andbatch-to-batch reproducibility. Thus UBC will conduct a series of pelletization tests with different mixturerecipe, pre-conditioning of material as well as adding binders. The produced pellets will then be tested for theircalorific value, chemical composition, chlorine content and ash content. The produced pellets will then betested for durability and hardness. This initial collaborative research and development between ICC Group andUBC is aimed at establishing a long term research partnership for optimizing the entire continuous process linefor making durable pellets from Refused Derived Fuel (RDF).
