초록

A gas turbine engine includes a combustor system including a lean premix combustor and a water delivery system. The combustor is operable with a fuel/air mixture equivalence ratio less than one and the water delivery system is configured to supply at least one of water or steam to the gas turbine engine such that either the water or the steam is injected into the combustor to control emissions generated by the combustor. As a result, nitrous oxide emissions for specified turbine operating power levels are lowered.

청구항

What is claimed is: 1. A method for operating a gas turbine combustor of a gas turbine engine using a water delivery system, the combustor including a plurality of domes, the water delivery system connected to the gas turbine engine, said method comprising the steps of: supplying at least one combustor dome with a fuel/air mixture equivalence ratio less than one; and separately supplying at least one of water and steam into the gas turbine engine with the water delivery system such that at least one of atomized water and steam is separately injected int...
