Experimental study has been carried out to investigate how the swirl intensity, in a swirl-stabilized premixed flame, affects on the flame structure and the emission characteristics for the application to the oxyfuel gas turbines. To analyze the flame structure, still images and OH radical"s chemiluminescence images of oxyfuel flames have been collected using a digital camera and an ICCD camera, respectively. Gas concentrations, NO<SUB>x</SUB>, CO and O<SUB>2</SUB>, have also been measured and used in the analyses.
Results reveals that the flame structure and the longitudinal distribution of CO within the combustor are strongly affected by the swirl intensity; at a higher swirl intensity, flames looked short and flat, consequently the CO disappeared rapidly to the down stream direction of the combustor; at a lower swirl intensity, flames are long-drawn and the CO remained longer to the down stream direction. Among various swirl intensities considered in this paper, 0.8 can be concluded as optimal design condition from the viewpoint of flame stability and emission characteristics; further investigation will be performed to justify the results of this paper.
