中文摘要:
      随着全球经济的快速发展,能源危机日渐凸显,太阳能作为可再生能源的一种,越来越受到人们的重视。因此,如何高效利用太阳能资源值得深究。熔盐具有良好的蓄热特性,在石化、电池及冶金行业中发挥着很大的作用,尤其可以作为传热蓄热介质应用于太阳能热发电和太阳能制氢中。其中硝酸盐的特性较为适合用于熔盐储热材料。主要针对硝酸熔融盐体系,一是介绍了硝酸熔融盐体系在太阳能方面的应用,二是介绍了国内外学者对此体系的物化性质研究,如工作温度范围、热力学性质及热稳定性等。通过对比,总结了不同混合熔融盐各项性能的异同。指出了硝酸熔融盐性能深入研究的方向,为硝酸熔盐在能源开发利用和环境保护等方面发挥更重要的作用提供了重要参考。
英文摘要:
      With the rapid development of the global economy, the energy crisis is becoming aculeate increasingly. As a new source of renewable energy, solar energy is attracting increasing attention. Therefore, how to achieve effective utilizations of solar energy resource is worth being further studied. Due to their excellent heat transfer characteristic, molten salts play a significant role in petrochemical, batteries and metallurgical industries, particularly in solar power generation and solar hydrogen production. Nitrate molten salts are good candidates for their excellent pro-perties of heat storage. The properties of nitrate molten salts is explored. On one hand, the application of the system in thermal energy storage is discussed. On the other hand, recent research progress on physical and chemical properties of the system is mainly introduced, such as the operating temperature range, thermodynamic properties, thermal stability and so on. Lastly, some new trends in their development are pointed out, which has unique importance to both energy development and environmental protection.
