    Networked factory stabilises the grid

    The factory of the future is flexible and networks the energy flows between machinery and buildings. The so-called Phi Factory is not only very energy-efficient, it also helps stabilise the electrical supply grid. The new model factory relies on a high share of renewable energy and helps smooth out electricity supply fluctuations.  more...
     

    Impact of defects can be calculated

    Large wind turbine components are made of cast iron with spheroidal graphite. During their production, however, chemical reactions can cause defects. These casting defects are called dross and their impact on component lifetime has, to date, only been evaluated using assumed material characteristics. There is a measure of uncertainty involved in providing evidence of their occurance. New non-destructive test methods should now be able to evaluate dross more reliably.  more...

    Reducing energy use from waste treatment

    Residual household waste lands in the grey waste container. It is either thermally exploited in a waste incineration plant, or it is taken to a plant for mechanicalbiological waste treatment. Here, the waste is sorted: Energy-rich parts are used for energy, while metals are recycled. The residues are treated in rotting boxes before disposal on landfills. The exhaust air from the process has to be purified. This takes up almost two-thirds of the energy consumption of waste treatment plants. Researchers, in collaboration with their project partners, have developed a more efficient method.  more...
     

    Processing and recycling titanium waste

    Titanium components account for up to 15 per cent of the total weight of modern aircraft. The material is light and very stable. However, up to 95 per cent of the original titanium is left over as waste chips during the entire manufacturing process. These are contaminated and until now it has not been possible to recycle them so that they are suitable for reuse in aircraft construction. Scientists have therefore developed a method that can process and recycle titanium chips with high purity.  more...

    Pilot production of thermoelectric modules

    Thermoelectric generators convert waste heat directly into electricity. They utilise temperature differences and are paving the way for more energy-efficient production processes. However, the technology has previously led a niche existence because the module production is labour-intensive and therefore expensive. Researchers from Freiburg now want to improve this.  more...
     

    Ceramic cube reduces gas losses

    Scientists have developed a new ceramic heat exchanger for industrial furnaces. This can transmit considerably more exhaust heat to the combustion media than the metal recuperators currently used in high-temperature furnaces in the process industry. The new ceramic recuperator thereby decreases the exhaust gas losses to less than 25 per cent.  more...

    Collectors putting the heat on the automotive industry

    Solar thermal energy has great potential up to 250 degrees Celsius. Apart from space heating and domestic hot water, only a fraction of it is used for other purposes. Therefore, researchers aim to make solar process heat usable in the automotive industry. A joint German-Austrian project has now been launched.  more...

    Pilot production launched for superconductors

    He had to wait 30 years for this moment: Dr Georg Bednorz, a Nobel Laureate in Physics, was present in the Rhineland town of Rheinbach to see the pilot production of high-temperature superconductors begin. It is intended to provide further insights into the manufacture of these almost resistance-free conductors and pave the way for their large-scale series production. The technology is therefore taking a further step towards market maturity.  more...
     

    Generating syngas from plastic wastes

    A newly developed gasification process utilises waste plastics, carbon-containing sorting residues and rubber parts as well as shredded materials in the automotive industry. It can also process chlorine-containing plastic streams with PVC fractions in an environmentally friendly and efficient manner. It produces a purified syngas without flue gas emissions. In the process, lime serves as a transport medium and simultaneously binds halogens and other harmful substances. The gas generated in the shaft kiln can replace valuable primary energy sources such as natural gas in high-temperature processes or be used to generate electricity in efficient gas engines.  more...
     

    Stadtwerke Augsburg testing superconducting fault current limiter

    The ASSIST project shows how decentralised feed-in systems can be safely integrated into a medium-voltage network. Since 15 March, a superconducting fault current limiter ensures that the electricity fed from a cogeneration engine test rig into the electricity grid belonging to Stadtwerke Augsburg municipal utility company is protected against short circuits. Last week, Thomas Janetscheck from Stadtwerke Augsburg presented the system at the ZIEHL V superconductor conference in Munich.  more...
