塔式与槽式光热电站蒸汽发生系统可靠性研究

Study on Reliability of Steam Generation System in Central Receiver Tower and Parabolic Through CSP Plants

在太阳能热发电(Concentrating solar power plant,简称CSP)领域,商业应用比较成熟有塔式和槽式技术。通过了解塔式与槽式机组的系统工作原理,了解塔式与槽式机组中蒸汽发生系统(Steam Generation System简称SGS)的组成和工艺流程,从光热机组整体设计、蒸汽发生系统设计、系统运行以及换热器本体优化等角度进行研究,为提高蒸汽发生系统的运行可靠性,提高光热电站运行的可靠性提供优化方案。

In solar thermal powerplant(concentrated solar power plant,abbreviated as CSP),commercial applications are more mature with Central Receiver Tower and Parabolic Through technologies.By understanding the working principles of Tower and Trough units,the composition and process flow of the steam generation system(SGS for short)in Tower and Trough units,this paper studies the overall design of the CSP unit,the design of the steam generation system,the system operation and the optimization of the heat exchanger body»etc.,and provides some ideas for improving the operational reliability of the steam generation system and the reliability of the CSP plant.
