Solar power plants with thermal energy storage using molten salt


Description

In order to keep the solar power station running continuously, the solar energy must be collected during the daytime and used in the evening. The Molten salt thermal energy storage device can solve this problem.

In the daytime, thermal energy storage device is used to heat HTM Therminol VP-1, then HTM Therminol VP-1 heat the HTM molten salt, and stored the hot molten salt in the storage tank. In the evening, the hot molten salt is used to heat the HTM Therminol VP-1 which can heat the water and generate steam. At last, the steam would drive a turbine and generate electricity.

The thermal energy storage device is an integrated system to collect and storage thermal energy. It consists of heat exchanger, high temperature storage tank, low temperature storage tank, transfer pump, valves, pipes and automatic control devices.

The supporting system of thermal energy storage device includes salt-dissolving system, start-up system, insulation & heat-tracing system and safety protection system.
