Heat Discharge of Molten Salt in Double Energy Storage Tank

The heat storage performance of double - tank molten salt tank is better than a single - tank system. In order to obtain the heat storage mechanism of double pot molten salt, the spiral coil heat exchanger was placed in the annular gap composed of the cylindrical baffle and open end tank wall. The energy release characteristics of the double tank are analyzed in detail. The results show that the cylindrical baffle can adjust the molten salt flow field in the tank, the outlet temperature of heat exchanger, the heat transfer capacity and the transient heat transfer effect. The results of this study can be used as the basis of double tank design.
