Solar Power Towers (SPT), also denominated Central Receiver Systems (CRS), are set up by a heliostats field which reflects solar radiation into a central receiver located atop a tower. These heliostats track the Sun with two axis. They are also considered as point focus collectors.
In solar thermal tower power plants with nearly planar mirrors focus solar radiation and direct it onto a receiver, which is located on the top of a tower. Very high temperatures in the receiver, resulting from this concentrated solar radiation enable generation of power plant process steam.
Main components of a solar tower are the heliostat field, the receiver, and the tower itself. A heliostat field is the sum of all heliostats of a solar tower. Heliostats are mirrors which are equipped with a two-axes tracking system in order to track the sun’s path.
All the issues commented above make solar power towers, among other concentrated solar power technologies, a promising technology with commercial possibilities in the mid term. Better performance and cheaper electricity compared with other options seems within reach.
By both systems, an increase of the capacity factor of the conventional power block of the solar tower power plant can be achieved. Through the integration of solar thermal storage or supplemental fossil or biomass firing, solar tower power plants produce dispatchable electricity to match peak demands at any time.
The development of solar tower power plants aims to use higher concentrating solar radiation compared to parabolic trough as the power plant process at higher temperature and therefore operates with better efficiency. Higher temperature is also an advantage for storage of thermal energy, as storage volume per unit of energy can be reduced.
