Abstract:
In this research work, we have conducted an experiment on the requirements of high temperature in solar thermal and thermal energy of solar concentrating. The mixed salts of (NaCl) Sodium Chloride, (MgCl₂) Magnesium Chloride, and (KCl) Potassium Chloride with a wide range of use and stable properties were selected in the solar heat‐transfer thermal storage system. Thirty‐six kinds of mixed chlorinated molten salts with different weight ratios were configured, using differential scanning calorimetric (DSC). The melting point of different proportions of molten salts was determined, and the results showed that the melting point of 36 kinds of mixed salts was concentrated which was distributed in the range of 400℃ and 465℃. On this basis, the specific heat of 11 different proportions of molten salts in the melting point near 400℃ was determined. The thermal storage cost was analyzed and the results show that the quality ratio of 2:7:1 for MgCl₂, NaCl, and KCl, respectively, and the lowest heat storage cost was the best heat storage medium. At last, the equation of the specific heat and temperature of the mixed salts in the molten state was obtained using the least square method. PRACTICAL APPLICATIONS: In this research paper, we have discussed and optimized heat storage and melting salts of solar energy with mixed salts of (NaCl) Sodium Chloride, (MgCl₂) Magnesium Chloride, and (KCl) Potassium Chloride with a wide range of use and stable properties were selected in the solar heat‐transfer thermal storage system. Thirty‐six kinds of mixed chlorinated molten salts with different weight ratios were configured, using differential scanning calorimetric (DSC). According to the experiment, the research work is beneficial for the development of remote, arid, and rural areas.
