Design and modelling of novel evacuated receiver tube of concentration solar power system by using heliostat stadium arrangement

Abstract

Abstract.A novel concentration solar evacuated receiver tube collector is proposed in this study. Details of design and simulation of the heliostat field are presented. The proposed system uses a heliostat stadium arrangement to focus sunlight towards a receiver (evacuated receiver tube). Heliostat field which looks like stadium arrangement is proposed an alternative system of the tower in the power tower plants to cancel the shading / blocking losses. In this study, simulation results showed that the energy input increases with increased solar irradiation; the increase ranges from 288 to 470W⁄m.The maximum amount of energy inputs that can be obtained in the receiver for the collector is around 470W/m for the maximum solar density of 688W⁄m 2 . In the solar is 402 W⁄m 2 , and the useful energy of collectors is about 288 W/m and the thermal efficiency of the receiver was around 23%.
