Abstract: A combined cycle power plant that includes a gas turbine engine, a heat recovery steam generator (HRSG), a steam turbine, a primary condenser, a condensate extraction pump, a gland steam condenser, and a cooling module. The HRSG generates steam. The steam turbine receives steam from the HRSG. The primary condenser is fluidly coupled to the steam turbine and receives a first portion of exhaust steam from the steam turbine. The condensate extraction pump is fluidly coupled to the primary condenser and receives a condensed first portion of exhaust steam. The gland steam condenser is fluidly coupled to the steam turbine and receives a second portion of exhaust steam from the steam turbine. The cooling module is fluidly coupled to the gland steam condenser and supplies a cooling fluid to the gland steam condenser. The cooling module is fluidly isolated from the condensate extraction pump.

Abstract: A fuel supply system includes a first component configured to direct a fuel flow to a combustor of an engine system. The first component includes a first inner surface and a first outer surface. The fuel supply system also includes an outer coating disposed on the first outer surface of the first component. The outer coating is configured to thermally insulate a first interior of the first component to reduce non-catalytic coke formation in the first interior. Additionally, the fuel supply system includes an inner coating disposed on the first inner surface of the first component. The inner coating is configured to reduce the fuel flow from contacting a base material of the first inner surface of the first component to reduce catalytic coke formation in the first interior.

Abstract: An inlet air filtration unit for a gas turbine includes an inlet filter house having an upstream surface through which air is ingested. A plurality of weather hoods is secured to the upstream surface. A wave-generating system is installed on or proximate to the plurality of weather hoods, the wave-generating system emitting waves that deter pests from the inlet filter house. A method of deterring pests from entering an inlet filter house of an inlet air filtration system is also provided. The method includes: installing a wave-generating system proximate to or on a weather hood on an upstream surface of the inlet filter house; and energizing the wave-generating system to produce energy waves across the upstream surface of the inlet filter house.

Abstract: Embodiments of the present invention provide an inertial filtration system for air-ingesting machines. The inertial filter 100 may comprise a reducer 133 downstream of a vortex generator. The reducer 133 decreases the area that the airstream flows through, which may increase the angular momentum and the centrifugal forces acting on the particles of the ingested airstream. This may increase the cleaning performance and a decrease in the pressure drop across the inertial filter 100. Generally, the inertial filter functions such that flow components of higher density are separated from the rest of the airstream. The higher density flow components are bled out of the inertial filter 100 via an outlet 135. The remaining flow components flow downstream to compressor section 535.
