These volumes present the Proceedings of the "Third Interna- tional Workshop on Solar Thermal Central Receiver Systems" or- ganized by the DFVLR and held in Konstanz, Federal Republic of Germany, June, 1986. The Workshop was the continuation of the conferences in Claremont, USA, 1982 and in Varese, Italy, 1984 on the subject of "Central Receiver Projects" and of the con- ferences in Stuttgart, Federal Republic of Germany, 1983 and in Atlanta, USA, 1985 on the subject of "High Temperature Solar Technology and Application." The success of the Workshop was indicated by the participation of 113...

The ener y crisis in 1973 and 1979 initiated a great number of activities and programs for low and high temperature applica tion of solar energy. Synthetic fuels and chemicals produced by solar energy is one of them, where temperatures in the range of 600-1000 C or even higher are needed. In principle such high temperatures can be produced in solar towers. For electricity tower plants production, the feasibility and operation of solar Solar Power has been examined during the SSPS - project (Small System) in Almeria, Spain. extend The objective of Solar Thermal Energy Utilization is to field...

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...

The results of a German research and development programme which provided the scientific basis for the realization of advanced solar technologies. The report covers developments in terminal concentrators, receivers, integrated receiver/reactors and solar chemistry processes.

The Technology Program GAST was executed from 1981 to 1987 as a German-Spanish joint program aiming at the development and the investigation of necessary solar specific components and software for a gas-cooled tower power station of medium size. After the tests had been successfully completed at the Plata- forma Solar de Almeria in 1987, the proceedings are now presented to inform the experts and the public about these developments and their results. Not intending to anticipate a detailed valuation of the results, however, we as the project monitors of the Technology program resume that the...

During the past decade, several heliostat development projects have been implemented in various parts of the world (MBB, ASINEL, MARTIN MARIETTA, ARCO SOLAR, etc.). These projects have concen- trated on the segmented glass mirror design, as used in the solar tower facilities of SSPS (Spain), BARSTOW (USA), THEMIS (France) 1] as well as in other test and prototype facilities. The main emphasis in these projects has been on the individually curved glass facets, on dimensioning, mounting and adjusting them, as well as on th structural rigidity of the system as a whole. Particular attention has...
