Application of hydrogen operated burners in the electric arc furnace

Abstract

Abstract The steel making industry has one of the highest carbon dioxide emissions worldwide. The recycling route with the electric arc furnace (EAF) as the central aggregate emits less carbon dioxide in comparison to the blast furnace. Still, the EAF offers high potential for a reduction of the carbon dioxide emissions. One possibility is the substitution of natural gas by hydrogen in the auxiliary burners of the EAF. This substitution is investigated and analysed using a dynamic EAF process model. The model is able to simulate the combustion of natural gas as well as hydrogen. The differences in the operating conditions and properties by the hydrogen operated burners can be analysed in the results of the EAF process model.
