Seminar on Solar Power Towers

Solar Power Towers is a good seminar topic for Mechanical students and other related branch and are also knows as 'Central Tower' power plants or 'Heliostat' power plants or power towers, is a type of solar furnace using a tower to receive the focused sunlight. It uses an array of flat, moveable mirrors (called heliostats) to focus the sun's rays upon a collector tower (the target).

Solar Power Towers

The high energy at now of targeted daylight is transferred to a substance that may store the warmth for later use. The more modern heat transfer material that has been with success incontestable is liquid Sodium. Sodium may be a metal with a high heat capability, permitting that energy to be keep and drawn off throughout the evening. That energy will, in turn, be accustomed boil water to be used in steam turbines. Water had originally been used as a heat transfer medium in earlier power tower versions (where the resultant steam was accustomed power a turbine). This method didn't yield power generation throughout the evening.

Recommended Project: Microcontroller based Time Operated Solar Tracking System

Solar power towers generate electric power from sunlight by focusing concentrated solar radiation on a tower-mounted heat exchanger (receiver). The system uses hundreds to thousands of sun-tracking mirrors called heliostats to reflect the incident sunlight onto the receiver. These plants are best suited for utility-scale applications in the 30 to 400 MWe range.

The heliostat field that surrounds the tower is set intent on optimize the annual performance of the plant. The sector and therefore the receiver are sized counting on the requirements of the utility. in an exceedingly typical installation, alternative energy assortment happens at a rate that exceeds the utmost needed to supply steam to the rotary engine. Consequently, the thermal storage system are often charged at constant time that the plant is manufacturing power at full capability. The quantitative relation of the thermal power provided by the collector system (the heliostat field and receiver) to the height thermal power needed by the rotary engine generator is termed the star multiple.
