Abstract
This seminar presents an experimental investigation of a novel nonpremixed gas turbine combustor designed for ammonia fuel or blended compositions. The study focuses on flame stability in terms of lean blowout for various fuel mixtures, flame chemiluminescence, and emissions, with a particular emphasis on hydrogen and ammonia blends. The results show that complete combustion of ammonia/H2 with low NOx levels under lean conditions is achievable. To address N2O emissions, variations in fuel H2 content, preheating, and dilution offer control mechanisms for both NOx and N2O. Increasing hydrogen content and preheating elevate NOx levels and conversely reduce N2O emissions. Air dilution decreases NOx levels while increasing N2O emissions. Furthermore, higher levels of preheating and dilution enable the transition to flame transparency and uniformity in the OH field, resembling the MILD combustion regime. Time-resolved 3D vortex structures of the swirl flow were quantitatively visualized by 4D Lagrangian particle tracking velocimetry.
