Abstract: An igniter for a combustor of a turbomachine includes a fuel inlet in fluid communication with a mixing plenum. The mixing plenum is positioned upstream of a mixing channel. An air inlet is in fluid communication with the mixing plenum and an ignition source is in operative communication with the mixing channel. The igniter may include a mounting flange configured for coupling the igniter to the combustor. The ignition source may be positioned proximate to a downstream end of the mixing channel and upstream of the mounting flange. The mixing channel may define a venturi shape. The venturi shape includes a converging section between an upstream end of the mixing channel and a venturi throat.

Abstract: A system includes a gas turbine system having a first compressor, a combustor, and a turbine, where the first compressor provides a first portion of a discharge air directly to the combustor. The system includes a fluid circuit which receives a fluid comprising a second portion of the discharge air from the first compressor or a combustible fluid and provides the second portion of the discharge air to fuel at a location upstream of the combustor to alter a chemical and physical characteristic of the fuel in an air-fuel mixture that is provided to the combustor.

Abstract: A system and a method for predicting and optimizing remaining hardware life of gas turbine components. Operating parameters of the gas turbine which may impact remaining hardware life are sensed and tracked using a plurality of sensors in communication with a control system including a computing device. Remaining hardware life is predicted using a physics-based hardware lifing model. The hardware lifing model may include an output of a filtration model configured to monitor contaminants based on a pressure drop across a filter. Optimizing the remaining hardware life is achieved by the control system adjusting one or more operation settings of the gas turbine.
