Molten salt tower solar thermal power generation principle: according to the principle of solar thermal power generation, the "light-heat-electricity" power generation method, thousands of heliostats are adjusted the angles by linear actuators to reflect sunlight to the surface of the heat absorber located at the top of the solar tower, forming a high temperature of more than 800 °C. Steam above 500°C generated by the heat transfer medium drives the steam turbine to generate electricity.
