• "Flameless combustion" of lean to ultra lean mixtures, supported by high-temperature burned gas, can resolve the dilemma between complete combustion versus ultra-low NOx emissions in gas turbine combustors. The characteristic of NOx emissions and combustion in "lean lean" two stage combustion was investigated for premixed-prevaporized kerosene-air mixtures using a coaxial flow configuration. A circular jet of secondary kerosene-air mixtures of lean to ultra-lean compositions were injected into the primary hot burned gas prepared by combustion of lean mixtures on an annular perforated flame holder The progress of reaction and NOx formation in the combustion tube were measured for non-swirled and swirled secondary jets. The conditions required for complete combustion of the secondary mixtures were defined for various ratios of secondary to primary air flow rates.
