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.

A drain system for a combustor of a gas turbine includes a plurality of drain tubes, a vertical header connected to an end of each drain tube to receive a fluid flow therefrom, and a horizontal header downstream of the vertical header and in fluid communication therewith. Each drain tube has another end adapted to be connected to a respective combustor can of the gas turbine to drain liquid therefrom. The vertical header is disposed at an angle between 30&#xb0; and 90&#xb0; with a horizontal plane.

A purge system and liquid fuel atomizing system, a system including a purge system and liquid fuel atomizing system, and a method of purging and atomizing are disclosed. The purging involves a first nozzle, a second nozzle, a third nozzle, and a staged compression system having a first stage and a second stage. The first stage is configured to selectively direct a first pressurized fluid stream to the first nozzle and the second nozzle. The second stage is configured to selectively direct a second pressurized fluid stream to the third nozzle.

A system, in one embodiment, includes an air injection system comprising a plurality of air injection tubes having a staggered arrangement, wherein each of the plurality of air injection tubes is configured to inject air into an exhaust duct.

System and method for injection of cooling air into exhaust gas flow

A combined cycle power plant includes a gas turbine having a first compressor, a second compressor downstream of the first compressor, and a regenerative heat exchanger between the first and second compressors. A steam generator is downstream of the gas turbine and receives exhaust from the gas turbine. A closed loop cooling system through the regenerative heat exchanger and the steam generator transfers heat from the regenerative heat exchanger to the steam generator. A method for operating a combined cycle power plant includes compressing a working fluid in a compressor and cooling the compressed working fluid with a regenerative heat exchanger so as to create a cooled compressed working fluid. The method further includes transferring heat from the regenerative heat exchanger to a steam generator.
