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...

Sensitivity of NOX formation to nitrogen release and char surface area: An estimation approach for CFD modelling of pulverized coal combustion

To effectively mitigate NO X emissions in pulverized coal combustion, Computational Fluid Dynamics (CFD) is frequently employed as a predictive tool. Because fuel-bound nitrogen is the primary source of NO X in these applications, modelling largely relies on coal characterization...
