The behavior of technically premixed CO2-diluted methane oxyflames is compared to operation with methane-air flames in a labscale combustor equipped with an axial-plus-tangential swirler. It has been shown in a former study that the stabilization reg

An experimental study is carried out to analyze effects of swirl on the structure and stabilization of methane non-premixed oxygen-enriched flames above a co-axial injector in which the two streams are eventually swirled. The mean position of the fla
