中文摘要: 介绍了日本某学术研究都市的分布式能源系统所采用的发电技术和余热利用系统,并对此系统的历年运行数据进行了分析.通过分析发现,燃料电池的余热利用效果不理想,其综合能源利用效率低;而燃气内燃机的余热利用较好,综合能源利用效率达到60%以上.因此提高整个系统的余热利用率是该系统优化运行的重要课题.
Abstract:This paper introduces the power generation technologies and exhaust heat utilization system of the distributed energy system in a science and research park in Japan and analyzes the system operation data.It is found that fuel cells have low comprehensive primary energy utilization efficiency caused by no-ideal exhaust heat utilization effect.As for gas engine,its power generation efficiency is closer to the rated value;in addition,gas engine also has above 60% high comprehensive primary energy utilization efficiency because of its high exhaust heat utilization efficiency.Thus,to raise the exhaust heat utilization efficiency is the important running strategy optimization issue for this distributed energy system.
