16.00 Uhr „WÄRMERÜCKGEWINNUNGSPOTENTIAL DURCH DIE GRÜNE TRANSFORMATION DER INTEGRIERTEN HÜTTE“ Thomas STEINPARZER - Head of Technology and Innovation for ECO Solutions, Primetals Technologies Austria GmbH Die Abkehr von fossilen Energieträgern durch die grüne Transformation der integrierten Hütte zu CO2-reduzierten bzw. -neutralen Stahl führt zu einer Reduktion der derzeit verfügbaren Hüttengase als auch einer Erhöhung der verfügbaren Abwärmemenge. Eine sinnvolle Nutzung dieser Abwärmeströme wird ein zukünftiger Baustein für den energieeffizienten Betrieb einer Hütte. Zukünftige Abwärmepotentiale als auch deren Rückgewinnungs- und Verwertungsmöglichkeiten werden in der Präsentation vorgestellt. 16.20 Uhr KAFFEEPAUSE 16.50 Uhr „ON THE WAY TO SUSTAINABLE THERMO PROCESS TECHNOLOGY – MODERN HEATING SYSTEMS FOR INDUSTRIAL FURNACES“ Krzysztof HORNIG - Vice President, Head of Division Furnaces Vasile JECHIU - Head of Department Burner Technology, ANDRITZ METALS Germany GmbH Modern humankind will continue to need the products of the metal industry in the future, similar to the products of other key industries. Especially in the field of energy-intensive thermal processes in the steel industry, the high demand for process heat supplied today by the oxidation of fossil fuels is required in terms of process technology. The reversal from fossil fuels is the core task of the transformation towards sustainable thermal process technology. Therefore, traditional energy sources are replaced with CO2-neutral alternatives, i.e., green electrical energy and green hydrogen. On the path to sustainable thermal process technology, however, the following simultaneous efforts are fundamentally important as well: • A further increase in the thermal efficiency of the process while reducing emissions as harmful as NOx or dust emissions. • A reduction in material loss within the production chain. For example, material loss occurs during the heating process due to scale formation. • An optimal interlinking of the individual production steps to increase the production chains‘ overall efficiency. • All-round use of intelligent, connected, and user-friendly automation systems. In the article, the innovative and practical solutions for heating systems in industrial furnaces for the steel industry are presented with the help of concrete examples. Furthermore, the complexity of the requirements for the industrial heating systems is analyzed. In particular, the latest developments with regenerative burners and hybrid heating systems are described here, which play a unique role in conversion towards sustainable thermal process technology.
