What is a thermal storage system?
The thermal storage system consists of heat exchangers containing thermal energy storage materials with different thermal energy storage temperatures, piping, valves and control units, as shown in Figure 2(a).
Which type of heat exchanger is used in thermal energy storage systems?
In this study, the MSH is a typical shell-and-tube heat exchanger, which is the most common type used in thermal energy storage systems . When the thermal load of the boiler is invariable, the thermal energy extraction from the flue gas (Qf) depends on the reduction of the heat absorbed by the working steam.
How is heat stored in a thermal power system?
The excess heat of the thermal power system is stored by the heat exchange between the heat sources (i.e., steam and flue gas) and molten salt. During the heat exchange between the steam and molten salt (Fig. 6), the molten salt is heated from 240.0 °C to 380.0 °C as steam is cooled from 600.0 °C to 311.0 °C.
