Abstract

A two-stage lean/lean gas turbine combustor was developed with low NOx characteristics in
each stage using small radial swirler of40mm outlet diameter in the pilot stage. Both flame tubes were arranged in series with the smaller combustor (76mm inside diameter) as the pilot stage and the larger combustor (l40mm inside diameter) as the main stage. The pilot stage was fuelled via vane passage fuel injector, while the main stage was fuelled around the wall of the exit plane of the pilot stage, using wall fuel injectors. Tests were conducted using propane as fuel. Low NOx emissions, as low as 2ppm were obtained when using fuel staging. A NOx
reduction of more than 40% was obtained at equivalence ratio of near 0.7, when using fuel
staging compared to the non-fuel-staging test. This was achieved with very small increase in
carbon monoxide emissions and almost no increase at all in the unburned hydrocarbon
emissions at the same equivalence ratio.
