[0002] Solar thermal power generation technology is an important direction for large-scale utilization of solar energy, and has far-reaching significance for humans to solve problems such as fossil energy crisis and air pollution. The working fluids used in solar thermal power generation include water (steam), molten salt, air, heat transfer oil, liquid metal and other heat transfer media. Among them, due to the volatility and discontinuity of solar illumination, a large-scale heat storage system must be installed in the solar thermal power generation system to generate electricity continuously and stably. The heat storage system stores the heat storage medium through a storage tank, and heats the heat storage medium through solar energy, so that solar energy can be stored in the heat storage medium. When the solar illumination is insufficient or heat is needed, the heat stored in the heat storage medium is released to realize the indirect utilization of solar energy. Molten salt has the characteristics of high use temperature, wide temperature range, good flow characteristics, large heat capacity, etc. Applying it as a heat storage working fluid to the heat storage system can just make up for the problem of unstable solar illumination, and it is currently the most widely used solar heat storage working fluid.
