Working of Solar Boiler Power Plant
The process of generating electricity in a solar boiler power plant can be broken down into several steps:
Solar collectors: The solar collectors, also known as heliostats, are made up of mirrors or lenses. That track the movement of the sun and focus its energy onto a receiver. Typically a boiler or a series of boilers.
Heat transfer fluid: A heat transfer fluid, such as synthetic oil or molten salt. It is used to carry the heat from the solar collectors to the boiler.
Boiler: The boiler is where the heat from the solar collectors is used to generate steam. The high-temperature steam is then used to drive a turbine.
Turbine: The turbine is connected to a generator. It is responsible for converting the kinetic energy from the steam into electrical energy.
Generator: The generator converts the rotational energy from the turbine into electrical energy.
Energy storage: Some solar boiler power plants may include energy storage systems. Such as molten salt storage tanks, to store excess heat generated during the day. And use it to generate electricity at night or during periods of low sunlight.
