摘　　要：高温熔盐蓄热技术是熔盐在新领域的又一应用,有着广阔的发展前景。本文介绍了高温熔盐的特性及常见熔盐的种类,比较其性能的优缺点,重点探讨了硝酸熔盐在太阳能热发电中的应用。通过实例的具体数据,对其应用的可行性进行了分析,结果表明硝酸熔盐更能减少发电系统成本,将是今后太阳能热发电中主要的蓄热和传热材料。High temperature molten salt thermal energy storage technology is another application for molten salt in new field. It has wide development trends. In this paper, the characteristics and categories for molten salt were introduced, the merit and demerit of its performance were compared. The applications of molten nitrate salt used for solar thermal power were emphatically discussed. From the example＇s detail data, their economy feasibility was analyzed. The results showed molten nitrate salt could reduce system cost and would be the primary thermal energy storage and heat transfer material in solar thermal power.
