Abstract
Approximately 30 % of the primary energy input of an electric arc furnace are lost in the off-gas, which is the biggest part of all energy losses. This article describes the iRecovery technology to recover this energy, especially targeting the reference project at Georgsmarienhütte in Germany. The result of this heat recovery is steam; it will be discussed why the question of steam usage is often more important and complex than the question of steam generation.
