Integration of the beam-down technology into SOLATOM's linear Fresnel solar field: Design and experimental results
The beam-down linear Fresnel solar field (BDLFR) is a concentrating solar technology that can irradiate linearly a heat flux on a ground receiver. This technology is developed for thermally processing high-density materials up to temperatures of 150–300 °C, such as asphalt aggregates. Here, the linear beam-down technology has been scaled-up and tested. SOLATOM's commercial linear Fresnel reflector has been re-adapted to a BDLFR. This demonstrator loop is located in Universitat Politècnica de València (39.47° N, 0.37° W) and consists of ten linear mirrors 50 cm wide, curved along the transversal axis, and oriented clockwise 18° from the East-West axis. Different beam-down configurations were studied for the design conditions, and once the design was established, it was built using ten flat 15 cm wide mirrors and coupled to a SOLATOM XL module. The modified solar field was tested on day 269 and the obtained heat flux was measured, achieving a peak of 4100 W/m2 for a direct irradiance of 640 W/m2, in two adjacent normal distributions due to misalignments and errors in the installation of beam-down. This was contrasted with Monte Carlo ray-tracing simulations, and with proper mirror alignment it is expected to achieve 7750 W/m2 under similar conditions.
期刊介绍：
Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
