Summary:A can-type gas turbine combustor with axial fuel staging (AFS) was developed to investigate combustion characteristics under natural gas and hydrogen co-firing. Experiments evaluated the effects of AFS fuel split and hydrogen content on emissions and stability. NOx emissions were minimized at an AFS split of ~16% across all hydrogen levels, while increasing hydrogen content slightly raised NOx and significantly reduced CO emissions. Higher AFS splits enhanced jet penetration, as shown by changes in the exit temperature profile. Combustion dynamics amplitude decreased at specific hydrogen contents, indicating the potential of AFS for stabilizing hydrogen co-firing. KCI Citation Count: 0
