Design and Implementation of Parabolic Trough Solar Thermal Collector

Abstract

The goal of this research paper is to design a parabolic trough solar collector that uses a steam engine for generating power through converged sunlight heat. The most effective shape for a solar collector is the parabolic trough shape because of its ability to focus sun's energy on a small focal point. The parabolic solar system uses concentrated solar power which uses mirrors and tracking systems to concentrate sunlight into a small area which generates sufficient thermal heat. This heat is utilized for generation of steam and the steam is used for operating a steam engine for producing electricity. A copper tube covered by a black layer is designed which utilizes heat transfer fluid (HTF) inside the metallic tube for producing steam. After producing electricity, the excess steam is utilized for generating safe drinking water. The developed model required very low collector surface area and the production cost is low.
