...L. O. Schunk; P. Haeberling; S. Wepf; D. Wuillemin; A. Meier; A. Steinfeld An improved engineering design of a solar chemical reactor for the thermal dissociation of ZnO at above 2000 K is presented. It features a rotating cavity receiver lined with ZnO particles that are held by centrifugal force...

... the product is again ZnO which can be reprocessed in the solar process step. This innovative concept will be scaled up to 300 kW solar input power within the so-called SOLZINC-project. In this paper we report on experimental results obtained with a two cavity reactor operated at solar power inputs of 3 - 8 kW...

...C. Wieckert A high-temperature solar chemical reactor for the processing of solids is scaled up from a laboratory scale ( 5 kW concentrated solar power input) to a pilot scale ( 200 kW ) . The chosen design features two cavities in series: An upper cavity has a small aperture to let in concentrated...

... be further reacted with H 2 O to form high-purity H 2 . In either case, the product ZnO is solar-recycled to Zn. We report on experimental results obtained with a 5 kW solar chemical reactor prototype that features two cavities in series, with the inner one functioning as the solar absorber and the outer one...

... may be controlled by several chemical and physical factors such as heat and mass transfer efficiencies, hydrodynamics and reactor design. The results of three complementary experimental approaches are reported. They are interpreted in connection with simplified models in order to describe...
