6 FAQs about [Principle of solar tower power station]
What is a solar tower?
A solar tower, also known as a solar power tower, is a way to concentrate solar power to make it a more powerful energy source. Solar towers are sometimes also called heliostat power plants because they use a collection of movable mirrors (heliostats) laid out in a field to gather and focus the sun at the tower.
How do power tower concentrating solar power systems work?
In power tower concentrating solar power systems, a large number of flat, sun-tracking mirrors, known as heliostats, focus sunlight onto a receiver at the top of a tall tower. A heat-transfer fluid heated in the receiver is used to heat a working fluid, which, in turn, is used in a conventional turbine generator to produce electricity.
How does a solar power tower work?
The Solar power tower consists of a field of thousands of mirrors (heliostats) surrounding a tower which holds a heat transfer fluid to concentrate light on a central receiver atop a tower (Fig. 1 c). Each heliostat has its own tracking mechanism to keep it focused on the tower to heat the transfer fluid, which is then used to run a turbine.
What are the operation modes of a solar tower plant?
