Tenova has recently been appointed by Arvedi Group, a European steelmaking specialist, to design and supply an iRecovery® system to be installed at the Arvedi factory based in Cremona, Italy. This new system will be implemented to an existing Tenova Consteel® system, which heats and feeds metallic charge to a 250-ton Electric Arc Furnace (EAF), for a combination of heat recovery and environmental sustainability. The start-up of the system is scheduled to take place at the beginning of 2017.
Heat recovery technology brings advantages during the operation phase, and the energy recovered can be flexibly used to process steam, heating purposes and power generation. At Arvedi, the Tenova iRecovery® system will recover 34,3 MW average of thermal power from the EAF production, corresponding to 52 t/h of average steam production, which will feed an Organic Rankine Cycle (ORC) turbo-generator provided by Turboden to produce electric energy (up to 7,5 MW) for Arvedi’s internal use. Furthermore, Arvedi’s steel plant will have a saving on electric energy consumption with a consequent reduction in CO2 emissions of approximately 23,300 t/y.
The iRecovery system can be installed to recover the energy from every kind of Electric Arc Furnaces and the combination of Consteel® and iRecovery® is among the most cutting-edge innovations that Tenova has introduced to the market.
