Solar receivers such as the Spiky Central Receiver Air Pre-heater (SCRAP) are important components of combined cycle concentrating solar power plants which provide the ability to deliver electrical power on demand through built-in thermal energy storage.
The potential of the novel SCRAP technology was evaluated by developing analytical and computational models to enable performance prediction. The computer models were validated against results from an experimental test setup developed and built for this purpose. The SCRAP receiver was shown to equal or exceed current technologies in terms of solar-thermal efficiency as well as the system pressure drop across it.
