Methods for reducing gas turbine engine emissions

A gas turbine engine includes a compressor rotor assembly including a first rotor, a combustor configured to operate with a fuel/air mixture equivalence ratio less than one, and a water injection assembly. The water injection assembly includes a water delivery system including a first plurality of s...

Zusammenfassung:	A gas turbine engine includes a compressor rotor assembly including a first rotor, a combustor configured to operate with a fuel/air mixture equivalence ratio less than one, and a water injection assembly. The water injection assembly includes a water delivery system including a first plurality of spray nozzles to supply water upstream from the first rotor. The water being supplied to the first rotor is atomized with the first plurality of spray nozzles prior to being supplied to the engine to lower the emissions generated by the combustor.
