To start the large-scale deployment of offshore wind in German waters, the German Federal Ministry for the Environment (BMU) supports the offshore test site "alpha ventus" in the North Sea with a research budget of about 50 million Euro in the next years. The overall objective of the research is to reduce the costs of offshore wind energy deployment in deep water. In order to provide all participating research projects with detailed data, the test site will be equipped with extensive measurement instrumentation.
This research initiative was named RAVE Research at Alpha VEntus and consists of a variety of projects in connection with the installation and operation of alpha ventus. As part of the RAVE initiative, so far the participating institutes and companies have prepared projects on the following topics:
Realization of the joint measurements and data management
Analysis of loads, modelling and further development of the different components of offshore wind turbines
Loads at offshore foundations and structures
Further development of LIDAR wind measuring techniques
Grid integration of offshore wind energy
Monitoring of the offshore wind energy deployment in Germany "Offshore WMEP"
Measurement of the operating noises and modelling of the sound propagation between tower and water
Ecologic research
Für die vollständige Rückgewinnung des in Edelstahlschlacken enthaltenen Chroms wird eine reduzierende Schmelzbehandlung im Elektro-Lichtbogenofen vorgeschlagen. Dabei wird das in der Schlacke enthaltene Cr2O3 zum Metall reduziert und in der schmelzflüssigen Phase separiert. Die Effektivität der Reduktion wird entscheidend durch die Fahrweise des Lichtbogenofens bestimmt. Mit optimalen Bedingungen lassen sich mehr als 90 % des enthaltenen Chroms als metallische Legierung zurückgewinnen
