Abstract
The heat transfer characteristics of molten salt for the storage of thermal energy were investigated. The temperature profiles and heat transfer coefficients during the storage and discharge stages were obtained with steam as the heat transfer fluid. Two kinds of inorganic salt were employed as the storage medium and two types of heat exchanger were tested in order to find the effect of heat exchanger configuration on the heat storage. The effects of the steam flow rates, the flow direction of steam in the storage tank, the temperature of the heat transfer fluid and the initial temperature of the discharge tank on the heat transfer were obtained and analyzed.
