两步双循环太阳能直接蒸汽发电系统研究

摘要

本文首先对太阳能直接蒸汽产生（DSG）技术中集热器已有的三种水循环方式进行分析探讨，在此基础上提出了两步双循环方式的太阳能直接蒸汽产生技术。在本次研究中，集热系统采用较为成熟的槽式集热系统。集热管采用压力泵雾化器喷雾给水方式，提高了集热管加热的效率，同时克服了水汽两相流问题以及很好的调整和平衡了不同时段内管道压力。%In this paper,Based on solar direct steam(DSG)of three kinds of water technology in heat exchanger has been analyzed,On the basis of the proposed solar direct steam two double cycle generation technology.In this study,The col ector system adopts trough mature solar heating system,Heat pump with pressure atomizer spray water supply system,Improve the efifciency of heat pipe heating.At the same time to overcome the problems of water vapor two-phase lfow and balance the different period of pipeline pressure.
