Control of oxidation in reheating operations
The CONSTOX three-year research programme, which was started in 2011, concerns control of oxidation in heating processes by adopting new combustion methods and alternative fuels.
The programme, which is carried out at the Lonato del Garda plant, was joined by Feralpi in partnership with research centres and other steelworks.
Partially funded by the European Community (RFCS), the programme focuses mainly on control of oxidation during billet heating in the rolling mills, through the optimisation of operating practices and the adoption of new combustion technologies and alternative fuels.
Heat recovery using ORC (Organic Rankine Cycle) technology
The Feralpi Group is co-partner of a programme entitled WHAVES – Waste Heat Valorisation for more Sustainable Energy Intensive Industries. Awarded by the Sustainable Industry Low Carbon scheme (CIP-SILC) initiative at the end of 2013, the programme is aimed at supporting industrial processes in pursuing a reduction of greenhouse gas emissions, while maintaining a competitive edge. The SILC initiative contributes to the achievement of the strategic objectives and energy efficiency established by the European Union.
This two-year research programme is funded by the European Committee as part of the SILC call for tender. It contemplates a feasibility study for the standardisation of the components of a plant for the recovery of thermal and electric energy from the offgas released by the electric arc furnace, possibly supplemented with other waste energy from the steel manufacturing processes.
WHAVES continues the process that started with the HREII (Heat Recovery in Energy Intensive Industries) and HREII Demo projects with the support of the Life programme of the Directorate-General for the Environment in the European Commission, with the aim to analyse the positive environmental effects and the potential of heat recovery using ORC (Organic Rankine Cycle) technology in Italy and Europe. The first prototype of an EAF heat recovery system using ORC technology was developed at the Feralpi Group member company ESF steel mill in Riesa, Germany (www.hreii.eu/demo).
The heat recovery system using ORC technology can be used in many industrial processes, contributing to their sustainability (reduced emissions as the result of avoided electricity consumption) and their competitive edge (energy saving reduces the cost of production).
The impact at a European level has a potential for avoided emissions up to 6 million tonnes of carbon dioxide a year, requiring investments in European technology estimated at 8 billion euros.
