IV. Blending mix usage in rolling mill pre-heating furnace for hard to abate industrial application, FENO, FVG, Italy

Industrial validation and implementation, in cooperation with the equipment supplier, of new burners(and relative piping, blending, and control systems) able to use renewable H2 blending with natural gas in reheating furnace of rebars rolling mills, to keep the billets at high temperature (typically 1,100-1,200°C) before rolling, to improve steel ductility, or to promote the formation of a specific microstructure. The prototypal reheating furnace will have to ensure at least the same level of safety during operation and quality of the product after rolling, surface quality in terms of scale formation, scale adhesion, and decarburization. Moreover, also air emissions will be verified in terms of CO2 reduction, and a particular focus will be devoted to NOX.

Considering the large consumption of the burners around 19 MSm3/year of Natural Gas, systems able to work in blends of H2/Natural Gas, up to 50% H2, will lead to a consequent reduction of the emission of CO2, and other GHG of about 10.000 ton/year.
