高温熔盐的制备及实验研究

Preparation and Experimental Study on High Temperature Molten Salt

为满足太阳能高温传热、蓄热的要求,分析了工业应用的高温热载体,制备了NaCl、KCl和无水MgCl2形成的新型高温熔盐,采用差示扫描量热法对混合熔盐热力学性质进行了测量,实验结果表明,高温熔盐具有较好的热稳定性,是一种理想的高温热载体．

To meet the requirement of high temperature of solar heat transfer and thermal storage, the industrial applications of the high temperature heat transfermaterials were introduced and a new kind of high temperature molten salt based on sodium chloride, potassium chloride and magnesium chloride anhydrous was prepared. Thermal properties of the molten salt had been measured by differential scanning calorimeter and the experimental results showed that it was applicable to high temperature storage. DSC analysis showed that the high temperature molten salt had preferable thermal stability and it was one kind of perfect high temperature heat transfer materials.
