Here's a breakdown of how solar towers work:
Heliostats: The solar tower system consists of a large number of flat, movable mirrors called heliostats. These heliostats are strategically arranged around a central tower and are programmed to track the sun across the sky throughout the day.
Concentration: Each heliostat reflects and concentrates sunlight onto a specific target on the tower, significantly increasing the intensity of the solar energy received.
Central Receiver: At the top of the tower, there is a receiver designed to absorb the concentrated solar energy. This receiver contains a fluid—commonly molten salt, water, or air—that captures the heat.
High Temperatures: The concentration of sunlight can generate extremely high temperatures in the receiver, often exceeding 500°C (932°F) and sometimes reaching up to °C (°F).
Heat Exchange: The heated fluid is then circulated through a heat exchanger, where its thermal energy is transferred to water, converting it into steam.
Electricity Generation: The high-pressure steam drives a turbine connected to an electric generator, producing electricity in a similar manner to traditional fossil fuel and nuclear power plants.
Thermal Storage: One of the advantages of solar towers is their ability to incorporate thermal energy storage systems, such as molten salt storage. This allows the stored heat to be used to generate electricity even when the sun is not shining, providing a more consistent and reliable power output.
Power Regulation: The electricity produced can be regulated by controlling the flow of steam to the turbine, enabling the power output to match demand.
Transmission: The electricity generated by the solar tower is then transformed to a higher voltage and transmitted to the power grid, where it can be distributed to consumers.
