Abstract
Large, robust and highly loaded secondary concentrators appear to be absolutely essential for solar thermochemical processes on an industrial scale. Operating experience shows that there is still a lot of work to be done in this field. A new type of modular air-cooled secondary concentrator with quartz glass protection is under development. Such a secondary concentrator with an inlet diameter of 3 m will become part of DLRs new 10 MW GFE test facility. Its commissioning is planned for 2027. With this facility, the secondary concentrators will be successively improved and validated for higher flux densities and temperatures.
