Research output: Contribution to journalArticlepeer-review


A novel technique for non-premixed low-NOx combustor design in which fuel is injected off-axis or asymmetrically into a whirl flame was developed. This approach was used to react methane and air in an atmospheric laboratory scale burner, resulting in low NO emission levels and modest CO emissions. NO emissions below 15 ppm were detected with associated CO below 25 ppm at 15% O2. The combustor displayed unusual stability even at overall equivalence ratios of less than 0.1. The design of the whirl combustor and a numerical analysis of the internal structure of the flame were presented. Original is an abstract.
