浅谈利用中低品位热源的有机朗肯循环发电技术

Discussion on ORC Power Generation Technologies by Applying Low/Medium Grade Thermal Sources

中低品位热源数量多、范围广,若采用有机朗肯循环技术回收利用该部分能量用以发电,不但能缓解能源危机,还可减轻因为余热所引起的环境污染,从而实现节能减排。为了给初步进入有机朗肯循环研究的人员提供一些相关的必要知识,本文在介绍有机朗肯循环的技术原理和应用领域之后,列举了数位学者对其在有机工质、设备优选和系统改进等方面的研究。有机朗肯循环发电技术广阔的发展前景引发了大量学者的探索,但在实际的推广应用方面,还有许多的现实问题需要克服。

Low - grade or medium - grade thermal energy can be obtained from multi - sources over widerange, which can reach the purposes of easing energy crisis and reducing air pollution if they are utilizedby Organic Rankine Cycle （ORC） technologies. After introducing both theoretical principles of ORCtechnologies and their applications, this paper delivers several crucial aspects of ORC - related resear-ches, including selection of working fluid, equipment configuration and integrated system improvement.The discussed issues in this paper provide the necessary knowledge for the beginners who study on ORCresearches. A lot of scholars have explored the potential prospective in .respect to ORC technologies, how-ever, there are mass investigation works to do before ORC can be validated in the practical field.
