摘要
硝酸盐凭借成本低、工作温度范围广等优点作为储热介质被广泛应用于聚光太阳能热发电系统。向硝酸盐中掺入纳米填料会使其传储热性能显著提高,可有效提高太阳能光热发电系统的发电效率。本文介绍了常见硝酸盐基纳米复合材料组分及制备方法,分析了纳米填料掺杂浓度和尺寸对硝酸盐纳米复合材料传储热性能的影响及其增强机制,最后指明硝酸盐纳米复合材料未来的研究方向。
Nitrates are widely used as heat storage mediums in the concentrating solar power system due to their low costs and wide operating temperature ranges.It can significantly improve the heat transfer and storage performance of the nitrates incorporated with nano-fillers,by which the power generation efficiency of the concentrating solar power system can further be improved.In this review,the components and preparation methods of nitrate composite materials were introduced.Then,the effects of the doping concentration and size of the nano-fillers on the heat transfer and storage properties of nitrate composites were analyzed.The enhancement mechanisms of the thermal performance were also summarized.Finally,the future research directions of the nitrate composite systems were outlined.
