Abstract: This disclosure describes examples of a filter media for use in filter devices, e.g., pulse filter cartridges found in power generating systems. Embodiments of the filter media include a base media and a membrane, which partially covers one or both sides of the base media. In one embodiment, the membrane covers a membrane area of at least one side of the base media, wherein the membrane area is less than a total area of the side on which the membrane is disposed.

Abstract: This disclosure describes embodiments of a vane conditioning apparatus for use in power generating systems. These embodiments generate one or more fluid streams, which impinge on vane separators in the power generating system to change the temperature of the vane separators. In one embodiment, the vane conditioning apparatus comprises a vortex tube to convert pressurized supply air to a hot fluid stream and a cold fluid stream. A flow control device couples with the vortex tube to regulates flow of the hot fluid stream and the cold fluid stream to the vane separators.

Abstract: Solutions for efficiently filtering air for a machine are disclosed. In one embodiment, a filter element for a filter assembly of a rotary machine is provided. The filter element includes: a first set of pleats, each pleat including a first tip radius and a first spacing; and a second set of pleats, each pleat including a second tip radius and a second spacing, wherein the first and second set of pleats are positioned upon a continuous filter media.

Abstract: A filtration apparatus includes at least three filter elements for filtering fluid, and a frame having a pyramidal frustum configuration that has at least three sides. The frame includes a frame structure for supporting the filter elements at the sides such that the filtration apparatus has a pyramidal frustum configuration. The filtration apparatus may be part of a filtration assembly. The filtration apparatus may be utilized within an associated method.

Abstract: A system includes a detector configured to detect a fog condition within an air flow directed toward a compressor. The system also includes a controller coupled to the detector, wherein the controller is configured to activate a first control measure in response to the fog condition.

Abstract: A filter element is provided for filtering air in an inlet system of a gas turbine. The filter element includes a hydrophobic filter media that limits the passage of particulates and liquid from passing through the filter element. The filter media extends along a longitudinal axis and circumferentially about a central passageway that extends along the longitudinal axis. The filter media further includes a plurality of pleats. The pleats extend in a non-linear or helical orientation about the longitudinal axis. Adjacent pleats define a trough portion extending therebetween. The orientation of the pleats reduces liquid from accumulating and pooling within the trough portion and promotes drainage of the liquid from the filter element.

Abstract: An exhaust flue is provided for use with a gas turbine engine. The exhaust flue is oriented to channel exhaust gases from a core engine of the gas turbine engine. The exhaust flue includes a radiating portion positioned within an air inlet of the gas turbine engine. The radiating portion is oriented to emit infrared radiation towards an air filter assembly within the air inlet.

Abstract: A filter cartridge assembly includes a first filter including a first cavity defined therein and a second filter coupled to the first filter. The second filter includes a second cavity defined therein in flow communication with first cavity. The filter cartridge assembly also includes at least one pre-filter extending about the first filter and the second filter such that a third cavity is defined between the at least one pre-filter and at least one of the first filter and the second filter.

Abstract: An apparatus is provided and includes an inlet, including a peripheral wall formed to define a pathway along which gaseous, fluidic and particulate matter flow and two or more nets sequentially disposed in the pathway, the two or more nets being suspended on the peripheral wall with substantially no clearance between each of the two or more nets and the peripheral wall and held sufficiently loosely to permit relative movement of each of the two or more nets such that an effective pore size of the two or more nets is variable over time to encourage fluidic condensation at the two or more nets and to permit a relatively substantial portion of the gaseous and particulate matter to continue to flow.
