Optimization of Photothermal System based on the Idea of Transmission Solar Energy via Optical Fibres

AbstractTaking into account the possibility of transport of concentrated solar energy using optical fibres, we predict what may be expected in solar furnaces making use of such fibres.The aims of this study are to optimize the coupling of a paraboloidal dish, which concentrates direct solar irradiance with dual axes tracking component, and the optical fibre, which transmits concentrated solar energy.We present review previous studies on the transmission of concentrated solar energy via optical fibres (TCSEvOF), and provide a mathematical model for coupling paraboloidal dish and the optical fibre.We present the daily power obtained at the output of the optical fibre, the power supply is estimated to be 25W at the end. Then we show that the energy transported is diffused until the enclosure then disperse inside it, this energy is absorbed by the receiver. Temperatures higher than 1600°K may be reached while maintaining very good efficiency. Such furnaces have the extra advantage of having temperature gradients which may be perfectly determined
