, developed in collaboration with Japanese Nipon Gases, the installation replaces traditional hydrogen oxy-fuel air gas burners. These advanced units combine pure oxygen and renewable hydrogen for combustion, which significantly improves thermal efficiency while providing cleaner flue gases. Since hydrogen combustion generates only water vapor, the process becomes a model for zero-carbon reheating operations.
Superheating furnaces typically account for up to 80 percent of total fuel consumption in a steel mill, making them one of the most energy-intensive assets in steel. By switching from fossil fuels to green hydrogen, the Sarrallet system significantly reduces the carbon footprint of steel production, a milestone for a sector responsible for almost nine percent of global carbon emissions.
