Electric Steelmaking
Recovering EAF offgas waste heat is a key to improve energy efficiency in electric steelmaking. EAF heat recovery with evaporation cooling and steam production is used more and more. When steam exceeds direct heat demand, energy conversion to electricity with organic Rankine cycle (ORC) is a proven solution. Various heat recovery systems, mostly operating in Europe since 2013, demonstrate how ORC can improve EAF steelmaking energy efficiency and economics. The largest of these plants, with a 7-MW electric power ORC, started up in 2018 at Arvedi Steel, making the EAF-based facilities in Cremona, Italy, one of the most efficient steel plants worldwide.
