Abstract: An apparatus for releasably clipping to a frame an element for removing particulates, impurities, and/or moisture from an air stream, the apparatus preferably comprising: a self-aligning attachment post; a clip which is longitudinally movable on the post; and a locking member which can be pushed inwardly on the post and which interacts with one or more locking tabs in a manner effective for compressing a biasing member and locking the biasing member in a compressed position for holding the clip in engagement with the element. The apparatus preferably also comprises a handle clip on the outer portion of the attachment post which can be pulled and rotated for installing or removing a second element and can be rotated to a second position and released such that the handle clip will automatically hold the second element on the frame.

Abstract: An improved silencer panel construction for use in the exhaust gas stream of power generation equipment is described. The silencer panel has an outer periphery of U-shaped channel. Perforated webbing is attached within the outer periphery to strengthen the outer periphery and reduce thermal gradients building up within the web during operation. Acoustical insulation is provided within the silencer panel and held in place by screening as well as perforated cladding. A plurality of silencer panels are spaced apart within the silencer chamber to attenuate the noise produced by the exhaust gas stream.

Abstract: An exhaust gas diffuser interface includes a stainless steel shell with varying levels of insulation. The varying levels of insulation concentrate thermal expansion and contraction at the turbine outlet end allowing it to be connected to the outlet by way of a seal weld. This construction allows expansion and contraction of the diffuser interface in unison with the attached turbine outlet, as well as the diffuser inlet.
