ESF Elbe-Stahlwerke Feralpi GmbH is one of Europe's most qualified iron and steel manufacturers, located in Riesa, Germany. The Feralpi Group is one of Europe’s leading manufacturers of steels for use in building construction.
Turboden focused on implementing an ORC unit to an electric arc furnace to produce electricity by exploiting the exhaust gases downstream formed after the process. The project was intended to be the first of its kind in building an ORC system to an electric arc furnace.
Turboden successfully implemented the first ORC-based heat recovery plant on an Electric Arc Furnace (EAF) in the world. The ORC unit exploits a portion of the saturated steam produced, while a parallel line delivers the rest of the stream (2 MW thermal) to a neighbor company for its own process. A total of 3 MWe output is achieved by the ORC unit.
The plant is a part of the H-REII DEMO Project (Heat recovery in Energy Intensive Industries) and was co-financed by the DG Environment of the European Commission under the LIFE+ program, thanks to the technological innovation and environmental benefits of the initiative.
