Gas burners play a crucial role in various ironmaking and steelmaking processes, particularly for heating and cutting operations. In Electric Arc Furnaces (EAFs), high-speed gas burners are widely used to enhance thermal efficiency. While the majority of heat in EAF is generated by electric arcs, gas burners help distribute heat more uniformly, improving overall energy efficiency. Currently, most of these burners operate with natural gas (primarily methane (CH4)) as fuel and oxygen or air as oxidiser. The gases are supplied through separate ports, forming non-premixed flames. As these flames impinge on scrap metal inside the furnace, heat is transferred primarily through convection and radiation to the scrap metal. However, despite their efficiency, these flames contribute to carbon dioxide (CO2) emissions, increasing the furnace’s overall carbon footprint. With the steel industry striving to reduce carbon emissions, hydrogen is emerging as a promising alternative fuel-particularly green hydrogen, which is produced with zero carbon emissions. Due to challenges associated with hydrogen transportation and storage, blending hydrogen with natural gas is becoming an economical transition strategy in the early stages of decarbonisation. However, before implementing this approach, it is essential to understand the combustion and heat transfer characteristics of hydrogen-enriched non-premixed impinging flames. Despite its significance, research in this area remains limited. This study aims to investigate the combustion and heat transfer behaviour of non-premixed flames impinging on a steel plate. A numerical approach using computational fluid dynamics (CFD) modelling, coupled with a thermodynamic combustion mechanism, is employed to analyse the flow field, combustion zone, and heat transfer characteristics. Large Eddy Simulation (LES) with the GRIMech3.0 combustion mechanism is applied to study different cases with 10 pct, 25 pct, 50 pct, and 75 pct hydrogen blending with natural gas and hydrogen flames. In all cases, the burner geometry remained identical, with only flow variables altered. The findings indicate that, despite hydrogen-blended fuels being supplied at a higher velocity than that of methane to maintain equivalent heat release, it results in approximately the same wall jet region as methane-impinging flame. The results show that the temperature of the flame increases as the hydrogen content increases in the flame. Also, flames with 100 pct hydrogen fuel are predicted to heat the steel plate to 735K compared to 665K for methane flame.
