项目摘要

The purpose of this research is to investigate the potential of cascade use of waste heat among energy intensive industries : iron & steel, cement, paper & pulp and ethylene. Firstly, regional energy-saving potential by heat cascading was evaluated in the actual local industrial structure in Japan. Secondly, spatial constrains of industries were introduced in the conbinat model to facilitate the evaluation of regional energy-saving. Thirdly,from the viewpoints of cost-saving potential as well as the energy-saving potential, new economic incentives, referred to as "energy tax" and "energy-tax refund", were proposed in consideration of the quality of energy use. Main results obtained in this paper are summarized as follows :1. Energy-saving potential by heat cascading highly depends on local industrial structure.2. Cascading between high temperature waste heat supply of ethylene and middle & low temperature heat and electricity demand of paper & pulp can provide high energy-saving.3. Oil consumption of steam boilers for the energy balance in a combinat can be reduced by more than about 90% by optimizing the industrial structure.4. Heat transmission loss will give little influence to the energy-saving potential in the optimized combinat.5. The conversion of waste energy into electricity is preferable, when considerable heat transmission loss is unavoidable.6. Economic incentives are effective to increase the energy-saving potential in the combinat optimized from the viewpoint of cost-saving potential.7. "Energy tax" in consideration of the quality of energy use promotes the introduction of heat cascading more economically than energy tax.8. "Energy-tax refund" based on exergy efficiency is more practical than "Energy tax", which can accomplish almost the same cost and oil consumption optimized from the cost-saving viewpoint as those optimized from the energy-saving viewpoint.

这项研究的目的是研究在能源密集型行业中级联热量使用废热的潜力：铁和钢，水泥，纸张和纸浆和乙烯。首先，在日本实际的本地工业结构中评估了级联热能的区域节能潜力。其次，在Conbinat模型中引入了行业的空间约束，以促进区域节能的评估。第三，考虑到能源使用质量，提出了提出提出的，从而省钱潜力以及节能潜力的新经济激励措施，称为“能源税”和“能源税退款”。本文获得的主要结果总结如下：1。热量级联的节能潜力高度取决于局部工业结构。2。高温废热乙烯与中和低温热以及纸张和纸浆的电力需求之间的级联可以提供高能量。3。通过优化工业结构，可以将蒸汽锅炉的油消耗用于组合中的能源平衡。4。热传输损失对优化的组合中的节能潜力几乎没有影响。5。当不可避免的是大量传输损失时，将废物能量转化为电力是可取的。6。经济激励措施可有效地提高从节省成本潜力的角度优化的组合中节能潜力。7。考虑到能源使用质量的“能源税”比能量税更经济地促进级联热量的引入8。基于发射效率的“能源税退款”比“能源税”更实用，它可以从节省成本的观点中实现几乎相同的成本和石油消耗，与从节能的观点优化的成本和石油消耗相同。
