Solar Parabolic Trough System (CSP)

System Description

These systems provide large-scale power generation from the sun and, because of their proven performance, are gaining acceptance in the energy marketplace. Parabolic trough is a type of solar thermal collector and a high performance & high efficient Parabolic Trough Concentrator Solar collector for use in Industrial process heat application and utility scale Solar thermal power plants. Parabolic-trough collectors can also drive absorption cooling systems or other equipment that runs off a thermal load.

Principle

By tracking the sun from sunrise to sunset, the parabolic Trough collectors concentrate the sun’s radiation with their parabolic mirror facets on the absorber tubes along their focal line. Through these absorber tube circulates a heat transfer fluid (HTF) and then deliver the thermal energy to a heat exchanger, where it generates steam for power generation or industrial processes. This fluid can be efficiently heated up to 4000C.
