Embodiment Construction

[0017] One or more specific embodiments of the invention are described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation may be described in the specification. It should be recognized that in the development of any such actual implementation, as in any engineering or design project, many implementation-specific decisions must be made to achieve the developer's specific goals, such as compliance with system-related and business-related constraints , which may vary from one implementation to another. Moreover, it should be recognized that such a development effort might be complex and time-consuming, but would not be a routine task of designing, producing, and fabricating, to those of ordinary skill having the benefit of this disclosure .

[0018] When introducing elements of various embodiments of the invention, the articles "a," "an," "the," and "said" are intended to mean that there are one or more of the...

Abstract

A turbocharger compressor noise attenuation device (60, 160) is formed separately from the air inlet (16) of the compressor housing (12). The device (60) includes a tapered inner surface (66) having a minimum diameter portion (62) that is axially spaced apart from a first end face (50), a maximum diameter portion (64) that is between the minimum diameter portion (62) an opposed second end (48), and an annular groove (72) formed in a working face (74) of the minimum diameter portion that is parallel to the first end face (50).

Description

technical field [0001] The subject matter disclosed herein relates to gas turbine systems, and more particularly, to air conditioning coil systems for gas turbine compressors. Background technique [0002] A gas turbine system generally includes a compressor, a combustor, and a turbine. The compressor compresses air from the intake and then directs the compressed air to the combustors. In the compressor, compressed air received from the compressor is mixed with fuel and combusted to produce combustion gases. Combustion gases are directed into a turbine. In a turbine, combustion gases pass through the turbine blades of the turbine, thereby driving the rotation of the turbine blades and the shaft to which the turbine blades are attached. Rotation of the shaft may further drive a load coupled to the shaft, such as a generator, and the temperature of the air supplied to the intake may affect the performance of the gas turbine system. For example, high temperatures reduce air...
