项目摘要

1. Mass balance, enegy yield, and cost estimation of RDF plant.1) Mass balance was estimated on composition base by using operation data and author's survey.2) Energy yield coefficient, defined by energy analysis technique, are positive for three RDF plants. Those for other two plants could be improved if the drying efficiency of refuse and the working ratio of the plant were improved.3) The total cost of RDF production, the sum of operation cost and construction cost, is 30-50 thousand yen per ton of input refuse for a midium size plant as 10t/d.2. Environmental impactHeavy metal contents in RDF,and in burned residue are less than those in unprocessed combustible waste, and in waste incineration residue, respectively. Both are satisfactory to landfilling criteria. When burned, effluent gas meets criteria with simple cyclon device.3. Model simulation1) Refuse for RDF production was simulated in three scinario : combustible waste, waste excluding food waste, and waste excluding plastics.2) Higher plastic content in input refuse leads higher volatile chlorine contents in RDF.So at least 50% of plastic should be excluded before the RDF processing to avoid the boiler corrosion problem.3) RDF production cost depends mainly on the scale of plant, depends less on the refuse sorting scinario.4) Less content of plastica in RDF reduces the energy yield to zero. So higher plastic content is favorable though chlorine removal device is required.5) Possible energy use were summarized.

1. RDF 装置的质量平衡、能量产量和成本估算。1) 通过使用运行数据和作者的调查，根据成分估算了质量平衡。2) 通过能量分析技术定义的能量产量系数对于三个 RDF 装置均为正值。如果提高垃圾干燥效率和工厂的工作效率，其他两个工厂的费用也可以得到改善。3）RDF 生产的总成本，即运行成本和建设成本之和，对于中型工厂（10t/d），每吨输入垃圾为 30-5 万日元。2。环境影响 RDF 和焚烧残渣中的重金属含量分别低于未处理的可燃废物和垃圾焚烧残渣中的重金属含量。两者均符合垃圾填埋标准。燃烧时，采用简易旋风装置，废气达标。 3．模型模拟1) RDF生产的垃圾分三种情况进行了模拟：可燃垃圾、除餐厨垃圾之外的垃圾和不包括塑料的垃圾。2)输入垃圾中的塑料含量较高，导致RDF中的挥发性氯含量较高。因此在RDF处理之前至少应排除50%的塑料，以避免锅炉腐蚀问题。3)RDF生产成本主要取决于工厂规模，依赖较少 4) RDF 中塑料含量较低，能量产量为零。因此，尽管需要除氯装置，但较高的塑料含量是有利的。5)总结了可能的能源使用。
