硝酸熔盐体系在能源利用中的研究进展

Research progress in application of molten nitrate salt in energy utilization

硝酸熔盐具有优良的传热和流体流动及易溶解无机物等特性,在熔盐传热蓄热、反应介质、熔盐电解液、废热利用、金属合金制造和高温燃料电池等方面得到广泛应用。介绍了硝酸熔盐在一般工业应用、太阳能热发电和太阳能制氢等方面的应用情况,指出随着对熔融硝酸盐性能深入研究和改进,硝酸熔盐在能源开发利用及环境保护等方面将会发挥更重要的作用。

Molten nitrate salt has an excellent heat transfer and fluid flow, easy to dissolve many inorganic compounds, so it can be used for heat transfer-thermal storage, reaction medium, electrolyte, waste heat utilization, metal alloy manufacture and high-temperature fuel cell. Its application in conventional industries, solar thermal power generation and solar hydrogen production is introduced. It is pointed out that molten nitrate salt will play a more important role in energy exploitation and environmental protection when the properties of nitrate salt are deeply studied and improved.
