Solar Concentrator, Outdoor Testing, Coil Receiver, Dish Solar ConcentratorAbstract
In this paper, design and fabrication of the parabolic solar dish concentrator for the steam generation have been carried out. The experimental setup consists of the parabolic dish of solar concentrator system is fabricated with highly reflective mirror. The concentrated heat is absorbed by a copper tube which is made up of coil in a curved shape and it is fixed on solar trace path to obtain maximum solar energy. The black coating over the receiver surface to reduce the various losses it is located in the focal point on the solar ray’s concentration and its core application in steam granulation coil receiver, heat transfer fluid as water and it is going through the system. The present study concerning the development and design of the parabolic dish solar concentrator indicates a diameter of 2.4 meters to obtain a concentration ratio of 91.16×. The outdoor experimental of a parabolic dish concentrator has been tested. The performance of parabolic dish concentrator studied for different experimental conditions. The outdoor experimental has also been carried out to estimate outlet temperature. The maximum temperature of 635 °C has been recorded, when the flow rate is 0.4 kg / min.
