Abstract: A gas turbomachine includes a compressor portion, a turbine portion operatively connected to the compressor portion, and a combustor assembly fluidically connected to the turbine portion. The combustor assembly includes at least one nozzle including at least one fuel gas injector portion and at least one water injector portion. A fuel system is fluidically connected to the at least one nozzle. The fuel system includes at least one fuel gas manifold, a water injector purge manifold and a water injector manifold. The at least one fuel gas manifold is selectively fluidically connectable to the water injector portion of the nozzle through the water injector purge manifold.

Abstract: A method and system for gas turbine emissions management through delivery of a diluent fluid stream (steam, CO2, N2 etc) into a gas turbine combustion system while the gas turbine is operating on a conventional fuel such as light distillate oil or natural gas. The diluent injection system delivers required diluent-to-fuel ratios over the emissions compliance operating range of the gas turbine. The method for diluent injection is coupling the injection system to a gas turbine compressor discharge purge system, such that the diluent fluid is mixed with compressor discharge air. The mixed compressor discharge purge air and diluent stream are injected into the gas turbine combustor through a non-fueled combustion fuel nozzle passage to achieve emissions guarantee compliance.

Abstract: A fuel system comprises a fuel nozzle having a first port and a second port, a first manifold connected to the first port, and a first inert gas buffer portion disposed between the first manifold and a source of compressed air.
