The sixth section details of components of solar power tower- Heliostat system, receiver system, thermal storage system, steam generator system and electric generation system. In seventh section discuss about advantage of solar power tower. The opportunity in India of this concept has discussed in eighth section.
In this paper solar tower structure is designed for a 50MW solar thermal power plant. A review of different types of towers used in solar thermal power plant is included at the start. Design process of tower structure is started by designing a tower structure based on the height requirement obtained from ray trace analysis.
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.
Solar Power Tower (SPT) produces electricity in an indirect way by the principle of Rankine cycle concept with regeneration, reheating concept. Solar power tower includes heliostat and concentrating solar power system. Solar energy in spite of being the most profuse energy source, it holds the shortcoming of available for only day time.
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.
There is a dire need to design new technologies for clean power generation. In this paper solar tower structure is designed for a 50MW solar thermal power plant. A review of different types of towers used in solar thermal power plant is included at the start.
