Abstract:
1. A combustion turbine air intake filter assembly comprising: a support; a filter alignment ring; and a plurality of filters comprising at least a high efficiency air intake filter, and an upstream filter; said support having a longitudinal axis and being attached to an air filter manifold, said manifold having a high pressure side and a low pressure side and at least one air passage therethrough, said support having a downstream end and an upstream end and extending essentially perpendicularly from said high pressure side of said air filter manifold, said upstream end of said support being configured to adjustably support one or more of said filters; said filter alignment ring having opposing first and second faces and extending concentrically around said at least one air passage through said air filter manifold and having an aperture therethrough, said first face being configured to form a sealed interface with said high pressure side of said air filter manifold, said second face comprising said aperture being aligned with said air passage in said air filter manifold, said ring having a raised wall extending circumferentially around said ring adjacent said aperture, said ring and said raised wall forming a surface for receiving an end of one of said plurality of filters and for preventing said end from substantial lateral movement, the interface between said receiving surface and said end of one of said plurality of filters forming a sealed abutment; said high efficiency air intake filter being concentrically disposed about a longitudinal axis and having an upstream end and a downstream end; said longitudinal axis of said high efficiency air intake filter and said longitudinal axis of said support being substantially aligned; said downstream end of said high efficiency air intake filter being open and forming a hermetically sealed interface with said filter alignment ring; said upstream end of said high efficiency air filter forming an aperture through which said upstream end of said support may be received and adjustably secured to said high efficiency filter to form a sealed interface between said upstream end of said high efficiency filter said upstream end of said support; said upstream filter being disposed about a longitudinal axis and having an upstream end and a downstream end, said upstream filter extending concentrically around said high efficiency air filter, said longitudinal axis of said upstream filter and said longitudinal axis of said support being substantially aligned; said downstream end of said upstream filter being open and forming a hermetically sealed interface with said filter alignment ring; said upstream end of said upstream filter forming an aperture through which said upstream end of said support may be received, said upstream end of said support being releasably and adjustably secured to said upstream filter such that, when secured, a sealed interface is formed between said upstream end of said upstream filter said upstream end of said support, and when released, said upstream filter may be removed from said assembly during turbine operation.
