Solar Thermal Energy Utilization. German Studies on Technology and Application: Volume 6: Final Reports 1990

The German R + D program “Solares Testzentrum Almeria” (SOTA) provides the scientific basis for the realization of advanced solar technologies including facility modifica-tions, component tests and new lines of development. One of the working packages, WP 300, addresses the “Scientific Support” by the performance of pre-paratory studies, exploratory laboratory activities and quali fied expertise. Universities, Research Institutes and Company R + D Entities in Germany are enabled to treat the following aspects: * Meteorological, system and cost investigations, * Development of important components as concentrator, receiver, storage, * Utilization of solar energy for process heat and chemical reactions. In 1990 the studies covered the developments of terminal concentrators, receivers, integrated receiver/reactors, and solar chemistry processes. The reports of the activities were finalized recently and collected in the present volume. The final reports were printed as received. The achieved results and the views ex-pressed within the reports were under the responsibility of the authors. As organizers of these solar thermal activities and as editors of the corresponding final reports, we would like to thank BMFT and KFA-BEO for the farsighted funding (grant no. 0328823A) and the research groups for their engagement and consultations. We would also like to thanl Solar-Thermal Power Generation with an Alkali Metal Thermo-Electric Converter (AMTEC).- Optimization of a Selective Volumetric Foil Receiver Detailed Heat Transfer and Flow Simulation.- Layout and Measurements of Terminal Concentrators.- Investigation of a Secondary Concentrator Model and of High Temperature Resistant Materials.- Corrosion Resistance of SiSiC Tube Material under the Specific Conditions of a Solar Heated Sulfuric Acid-Iodine Process Plant.- Fundamentals of Combined Thermal and Photochemical Decomposition of Sulfur Trioxide at High Temperatures.- The Use of Thermal Solar Energy to Treat Waste Materials Part 2.- Study Relating to the Use of Solar Energy for the Allothermal Gasification of Coal.- Solar Powered Energy Cycle with Coupled Biomass Production by Chemoautotrophic Bacteria.- Preparation and Characterization of Novel Mixed Titanium/Iron Oxide Photocatalysts for the Detoxification of Polluted Aquifers.- Model Compounds for the Oxidation of Water in Photosynthesis.- Chemical Use of Photonic Solar Radiation – Photochemical Syntheses (I).
