steelTalks is a monthly series on topics of interest to the global steel community. The lectures are presented in a webinar format with a guest lecturer. In this webinar, Joachim von Schéele, Global Director Commercialisation at Linde, explains how energy-efficient oxyfuel combustion supports decarbonisation in steel production and how hydrogen can be integrated into combustion systems without compromising performance. The session outlines the fundamentals of combustion processes, the benefits of conventional and flameless oxyfuel technology, and its applications in electric arc furnace (EAF) burners, ladle preheating, and reheating operations.
