Among them, solar thermal power generation plays an irreplaceable role in energy transformation and promoting the high-quality development of renewable energy. Tower solar thermal power generation uses heliostats arranged on the ground to reflect sunlight onto the absorber at the top of the tower, and converts the accumulated solar radiation energy into thermal energy on the absorber to heat the internal heat transfer fluid. After reaching a certain temperature, it is transported to the ground through a pipeline and stored in a high-temperature molten salt storage tank. When generating electricity, the high-temperature molten salt is transported to the steam generator system through a high-temperature molten salt pump for heat exchange with the turbine feed water, generating high-pressure superheated steam to drive the steam turbine generator set to generate electricity. Therefore, the installation of heliostats occupies an important position in the implementation of the entire solar thermal power generation project.
