Abstract:The Directly Irradiated Annular Pressurized Receiver (DIAPR) is a volumetric (directly-irradiated) windowed cavity receiver, designed for operation at a pressure of 10–30 bar, exit gas temperature of up to 1,300°C, and aperture radiation flux of up to 10 MW/m2. This paper presents test results obtained under various irradiation conditions and flow rates. Inlet aperture flux was up to 5 MW/m2; exit air temperatures of up to 1,200°C were obtained, while operating at pressures of 17–20 bar. Estimated receiver eff… Show more
“…Note, however, that the solar STIG cycle does not offer a way to approach 100% solar operation. Other solutions can be developed to achieve this goal, for example direct solar heating of compressed air up to the TIT (Kribus et al, 2001).…”

“…Alvarez et al [37] developed a system model for the Technology program Solar Air Receiver (TSA) plant. Kribus et al [38] introduced the development of the Directly-Irradiated Annular Pressurized Receiver (DIAPR) components and predicted the performance of a receiver operating at 20 bar and 1200°C. As for the STPP with open-loop air system, a 1.5 MWe solar tower power plant with an open-loop air system was built in Julich, Germany with an open volumetric air receiver.…”
“…The solar gas turbine system is another promising hybrid solar/fossil technology. Pressurized air receivers are used in solar tower plants to heat the compressed air in the gas turbine to temperatures up to 1000 °C or higher [6,7,8].…”
