Abstract: A filter bag assembly includes a first filter bag having at least two sidewalls of filter material extending from an open end to a closed end of the first filter bag at which the sidewalls connect to close the first filter bag. Two of the sidewalls of filter material are opposed to each other across the first filter bag and spaced from each other at the open end of the first filter bag. The two sidewalls are configured to form a tapered pocket, and the first filter bag includes a plurality of tapered pockets. A substantially rigid mesh is in contact with the first filter bag. The mesh is configured in a substantially V-shape and located near the open end of the first filter bag. The mesh is configured to maintain a shape of the tapered pockets and reduce filter pressure loss during use of the filter bag assembly.

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: This disclosure describes examples of a seal element that can prevent leaks that occur due to sagging and/or displacement of a filter device from the tubesheet in a power generating system. The seal element can have a non-uniform profile that defines a material thickness for the seal element. In one example, the non-uniform profile defines an area or section of the seal element that is thicker relative to other areas or sections of the seal element. The thicker area corresponds to certain positions on the filter device that are susceptible to movement that can occur, e.g., due to particulate build-up during operation of the turbo-machine.

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.

Abstract: An adaptive vane separator system is provided for use with an inlet filter house of a gas turbine engine system. The vane separator system is coupled to the inlet filter house. The vane separator system includes a slide rail and a plurality of vanes rotatably coupled to the slide rail. The inlet filter house is configured to channel air to an air inlet of a turbine engine. A drive motor is coupled to the vane separator system. The drive motor is operable to selectively move at least one of the vanes to facilitate reducing an amount of moisture channeled through the air inlet.

Abstract: This disclosure describes embodiments of a filter device for use in power generating systems with turbo-machines. In one embodiment, the filter device comprises a two element filter set, having an inner element and an outer element. The inner element resides inside of the outer element to reduce the overall length of the filter device. In one example, the filter device mounts to a wall, or tubesheet, found in an air filter unit of the power generating system.

Abstract: A moisture reducing apparatus is provided that includes a housing configured to receive an air stream and a net disposed outside the housing. In the apparatus, the net is held sufficiently loosely to permit movement of the net such that flow through the net is variable over time to remove moisture with the net and to permit a relatively substantial portion of a gaseous and particulate matter in the air stream to continue to flow through the net and inside the housing to protect filter media from moisture.

Abstract: A monitoring system for monitoring the integrity of a member disposed within a machine includes an image analyzer configured to receive image data from an imaging device and to determine an amount of radiation incident on one or more of one or more pixels of the imaging device.
