Study on Molten Salt Storage Systems and Application Prospect of Heating System Using Molten Salt Storage System

液态熔盐由于体热容量大;低粘度、流动性好;低蒸汽压;较宽的工作温度范围;同时还具有较大的裂变材料溶解度,可用于熔盐堆中的最为燃料溶剂;是核能及太阳能传蓄热应用中良好的热工介质。本文结合典型熔盐的特点及应用对熔盐储能技术的研究进展进行了综述,并重点介绍了熔盐供暖技术的应用前景。熔盐储能供热利用熔盐极佳的储热特性,具有安全、环保、经济等特性,是目前最具竞争优势的供热方式。

Molten salt is an ideal medium for heat transfer and storage in nuclear reactor and concentrated solar power system because of its low viscosity, low vapor pressure at high temperature, large specific capacity, ＇high thermal conductivity and wide temperature range. A state-of-the-art review on the development of molten salt storage systems integrating with characteristics and applications was provided. The outlook of future development of molten salt storage systems in household heating system was recommended. Molten salt storage energy heating using molten salt excellent heat storage characteristics, with safety, environmental protection, economic and other characteristics, was the most competitive way of heating.
