    Heat storage system replaces steam boiler

    The world’s largest high-temperature latent heat storage system reached its future deployment site, the Wellesweiler cogeneration plant of STEAG New Energies GmbH in the Saarland, upon a flatbed truck mid-September. The system is intended to ensure permanent steam supply to an adjacent plant for the production of plastic sheeting. To date, operation of an additional heating boiler has been required under continual minimal load. This currently takes over short-term steam supply in the event of a malfunction of the power plant turbine until a steam boiler is initiated.  more...
     

    New Energy Research Programme published

    The German cabinet has passed the new, 7th “Innovations for Energy Transition” Energy Research Programme. The programme replaces its predecessor from 2011. Content-wise, the programme builds on the successes of recent years, sets new courses and defines focal points for research funding and innovation policy in the energy sector. For the years 2018-2022, the German Government is budgeting 6.4 billion euros for energy research.  more...
     

    Solar water heater for ceramic granules

    The innovative CentRec radiation receiver has passed its first practical test at very high temperatures in the DLR’s solar tower in Jülich. The receiver uses ceramic particles as a heat storage medium. These are inexpensive, enable very high temperatures and can be handled with relatively little effort. The practical test at very high temperatures is an important step on the way to marketing this receiver technology.  more...
     

    Using bionic surfaces on blast furnace

    In blast furnaces, air approx. 1,200 °C in temperature is blown into the reaction chamber for the reduction and melting process of iron. Special water-cooled nozzles made of copper are used for this, known as blow moulds. These are susceptible to damage or destruction by red-hot droplets of iron. This then costs time and money to put right. Researchers have now been able to design the surfaces of these blow moulds to allow liquid iron to simply drip off. This new beading effect is similar to the lotus effect seen on leaves.  more...
     

    Solar process heat

    Around three-quarters of the final energy consumption in the industrial sector in Germany is caused by process and space heating. Solar heat can be used in many different ways in the low-temperature operations in particular, as well as in the commercial, trade and services sectors. International studies confirm the global potential for this technology.  more...

    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...
     

    FLOX burners turn mega

    In many high-temperature processes, so-called FLOX burners provide optimum fuel utilisation with low pollutant emissions. Flameless oxidation – known as FLOX – has already become established in the middle output range between 20 and 300 kilowatts. Scientists are now working as part of the Mega-FLOX project to expand the output range. This opens up new areas of application.  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...

    Metal foam – a material for heat engineering

    Metal foams are increasingly developing into materials with diverse uses. While metal foams with closed pores have already become established as rigid and strong lightweight materials, the open-cell variant is suitable for thermal engineering applications. Until now, the material has been rarely used in heat exchangers or coolers because the production is expensive and its application little tested. Researchers at the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM in Dresden now want to change this.  more...
