摘要

提出了一种采用爪式发动机的新型反射塔底式太阳能集热式发电系统

设计了该发电系统的结构和流程。分析了该发电系统在不同压缩比和集热温度下有回热和无回热两种情况下的循环效率。结果表明:发动机包括2级爪式压缩机和两级爪式膨胀机

将其同轴串联

具有干式无油、结构紧凑、自动平衡轴向力等优点;有回热的爪式发动机发电循环适用于压缩比较低、集热温度较高的应用场合

而无回热的发电循环适应于压缩比较高、集热温度较低的应用场合。

Abstract

A novel solar thermal power generation system was presented

which was the new central receiver system with beam-down reflectors. The structure and process of the new system were designed. The new claw engine included two-stage claw compressor and two-stage claw expander

which were coaxial series connection. So the claw engine had many advantages

such as dry oil free

compact structure

automatic balance axial force

and so on. The electricity generation cycle system realized employing displacement compressor and displacement expander

isobaric heat absorbent process

to complete power generation process

so that it had the high electricity generation efficiency. The change regulation of circle efficiency with and without extra heat-exchange

influenced by different compression ratios and heat collecting temperature were obtained.
