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
