摘要

众所周知，熔盐是热能储存（TES）系统中常用的相变材料，可提高聚光太阳能发电厂（CSP）对太阳能的有效利用和储存。在这里，三维 TES（3DTES）是由高孔隙率（高达 ∼ 90 %）的三维打印图案化蛭石（V）和氧化铝（Al2O3）支撑物制造而成的，这些支撑物已渗入熔融硝酸钠盐（nn）和太阳能盐（ss）。这些 3DTES 已在抛物面太阳炉中的真实聚光太阳辐射条件下进行了验证。在不同的 3DTES 中，基于 V-nn 的 3DTES 将入射太阳辐射转化为热量的效率最高；而 Al2O3-nn 则能更有效地传递热量，并且由于其热传导率更高，充放电循环速度更快。这项研究证实了增材制造在为 CSP 应用开发新型创新 TES 方面的优势。

Thermal energy storage behaviour of 3D ceramic/molten salt structures under real concentrated solar radiation

Molten salts, phase change materials commonly employed in thermal energy storage (TES) systems, are widely known to enhance the efficient use and storage of solar energy in concentrated solar power (CSP) plants. Here, three-dimensional TES (3DTES) have been manufactured from highly porous (up to ∼90 %) 3D printed patterned vermiculite (V) and alumina (Al₂O₃) supports, which have been infiltrated with molten sodium nitrate salt (nn) and solar salt (ss). These 3DTES have been validated under real concentrated solar radiation in a parabolic solar furnace. Among the different 3DTES, those based on V-nn exhibits the best efficiency for the conversion of the incident solar radiation into heat; whereas Al₂O₃-nn transfers the heat more efficiently and allows a faster charging-discharging cyclability due to its higher thermal conductivity. This study confirms the benefits of additive manufacturing to develop a new class of innovative TES for CSP applications.

期刊介绍： The Journal of the European Ceramic Society publishes the results of original research and reviews relating to ceramic materials. Papers of either an experimental or theoretical character will be welcomed on a fully international basis. The emphasis is on novel generic science concerning the relationships between processing, microstructure and properties of polycrystalline ceramics consolidated at high temperature. Papers may relate to any of the conventional categories of ceramic: structural, functional, traditional or composite. The central objective is to sustain a high standard of research quality by means of appropriate reviewing procedures.
