A solar power tower, also known as 'central tower' power plant or ' heliostat ' power plant, is a type of solar furnace using a tower to receive focused sunlight. It uses an array of flat, movable mirrors (called heliostats) to focus the sun's rays upon a collector tower (the target).
Only two types of solar tower concepts will be described here in greater detail. The first type of solar tower is the open volumetric receiver concept (see Figure 4a). A blower transports ambient air through the receiver, which is heated up by the reflected sunlight.
In hybrid plants, the solar energy can be used to reduce fossil fuel usage or boost the power input to the steam turbine. Today, many areas of the developing world like India, Egypt and South Africa, are in need of new peaking and intermediate power sources and these locations are ideally suited for power tower development.
In summary, the power tower concentrating solar power plant, at the heart of which lies the heliostat, is a very promising area of renewable energy. Benefits include high optical concentration ratios and operating temperatures, corresponding to high efficiency, and an ability to easily incorporate thermal energy storage.
The operation in very high temperatures with the solar tower is a critical issue that needs the selection of the proper working fluids. The molten salts or water/steam working fluids are usually used for operation up to 550 °C and coupling the system with a Rankine cycle .
