| Abstract Scope |
The steel industry’s long-term efforts to reduce carbon emissions have pushed the exploration of green hydrogen as an alternative to natural gas. The reheat furnace, a crucial component of iron and steelmaking operations, relies heavily on natural gas. Given the substantial contribution of the industry to global CO2 emissions, the transition from fossil fuels to greener alternatives is imperative. In this study, we explored the feasibility of incorporating hydrogen into the reheating process by using a baseline reheating furnace fueled by natural gas and analyzed the impact of different blend percentages of hydrogen on furnace temperature and steel slab temperature using computational fluid dynamics (CFD) simulations. Slab temperatures were obtained at the end of slab heating simulations by way of an iterative approach using frozen-flow transient simulations. The present research not only highlights the potential of hydrogen-natural gas blends to cut down the CO2 emissions of the reheating process. |
