Soltrec - high temperature pressurized volumetric air receiver
Main Info
Eureka International Cooperation Project “Soltrec”
� Abengoa Solar NT - “Soltrec I” Funding by CDTI (Spain)
� DLR & Heraeus - “Soltrec II” Funding by BMU (Germany)
Refos-The feasibility of the pressurized volumetric receiver technology with secondary concentrator has been proven. Testing different absorber types for different temperatures.
�Solgate�Successful demonstration of the combination of a gas micro-turbine and a pressurized volumetric solar receiver, at a power level of 230 kWel.
�Solhyco�First demonstration of a 100% renewable electricity generation with a commercial gas turbine based on biofuels.�Successful modifications on a commercial 100 kWel helicopter turbine. �First conical tubular receiver.
Refos Volumetric Receiver

Previous Experience
Solhyco tubular receiver
• Compressed air receiver outlet temperatures up to 1000 °C, combining:a) Tubular receiver until 800 ºCb) Volumetric receiver 800 – 1000 ºC
�Solar field configurations with multiple receivers and cavities leads to optimization of cost, O&M, usage of different incidence angles and flux distribution of focal spot
