    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...
     

    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...

    Steel pistons for more efficient diesel engines

    With a new cooling concept, an automotive industry supplier is expanding the range of applications for steel pistons in diesel engines. The Stuttgart-based company is testing a liquid alloy comprising sodium and potassium, which dissipates heat from the particularly thermally loaded piston head. This innovative steel piston concept is designed to enable even further increases in the specific power of car diesel engines. In the case of long-running engines for industrial applications and commercial vehicles, the component and engine oil load is significantly reduced while the expected service life and oil change intervals are prolonged.  more...
     

    Exhaust heat cools lorry cab

    Time for a break! The driver stops his lorry at the truck stop. To ensure that the cabin also remains cool even in summer, the engine also continues idling when the lorry is parked, often for hours. This produces noise and wastes fuel. However, researchers at the University of Stuttgart have now demonstrated that pleasant temperatures can still be reached even when the engine is switched off and there are no additional energy inputs. They have developed a special adsorption chiller. This utilises the exhaust heat produced while driving for air-conditioning the parked vehicle.  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...
     

    Cooling with solar heat

    The cooling or air conditioning of buildings with solar heat has a particular appeal because the heat demand and supply are usually consistent with each another. Cold stores in southern climates and many process refrigeration systems also require considerable energy when the sun shines intensely. The use of solar cooling systems instead of electric chillers also eases the grid, particularly at peak load times.  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...
