Effects of hydrogen–coal mixing on NOx formation during partial decarbonisation of rotary kiln iron ore induration - pilot-scale experiments using spectroscopy and video analysis

This pilot-scale study examines hydrogen–coal co-firing at 0–65% hydrogen energy substitution in a 580-kW furnace representative of industrial iron-ore kiln systems. Five burner families, comprising six tested configurations, varied the relative positions, injection directions an...

The Effect of Pre-oxidation on the Hydrogen Reduction of Magnetite Ores at 973 K: Role of Particle Size and Gangue Chemistry

This study systematically investigates the effects of controlled pre-oxidation on hydrogen-based reduction of three industrial magnetite ores, distinguished by their gangue chemistries (CaO, negligible gangue, and MgO), and examines two particle size fractions. Pre-oxidation beha...
