Preheating chamber for cold metal at Hydro Husnes

Hydro is building a preheating chamber for cold metal at the Husnes casthouse. The preheating chamber will utilize exhaust fume gas from the casting furnaces to preheat cold metal to approx. 300oC, thus recycling excess heat and save energy (natural gas). The plan was to have the preheating chamber in full operation from May 2020. This delayed until March 2021 due to the COVID 19 pandemic. Based on concept design, initial modelling and assessments, the reduction in energy consumption is estimated to be around 214 kWh/t cold metal with a preheating chamber based on recycling heat from flue gas. There will be a corresponding reduction in CO2 emission due to reduced usage of natural gas. The total budgeted cost is 17,6 MNOK. Hydro is applying for 26% support from Enova (4,59 MNOK). Hydro will finance the remaining cost.
