AI Technical Summary

Problems solved by technology

For example, enclosures are heavy and difficult and expensive to manufacture due to material costs and the need for welding to form tubes or panels
In addition, the panels must be welded to the location of the surrounding metal tubes and must be custom fit for specific size tubes

Embodiment Construction

[0067] As described above, the present disclosure provides a muffling duct and a turbine inlet including the muffler duct.

[0068] See attached picture, figure 1 An exemplary industrial machine in the form of a turbine 10 (eg, a simple cycle gas turbine power generation system) is depicted, which may include a gas turbine system 12 , among other things. Gas turbine system 12 may combust liquid or gaseous fuels, such as natural gas and / or hydrogen-rich syngas, to generate hot combustion gases to drive gas turbine system 12 . Gas turbine system 12 includes an intake section 16 , a compressor 18 , a combustor component 20 , and a turbine component 22 . Turbine member 22 is drivingly coupled to compressor 18 via shaft 24 . In operation, air (eg, ambient air) enters the gas turbine system 12 (indicated by arrow 26 ) via the turbine inlet or intake section 16 and is pressurized in the compressor component 18 . Inlet 16 may include an intake frame 17 for forming a flow of working...

Abstract

A silencer duct that may be part of, for example, a turbomachine inlet may include a duct body. A first perforated wall extends within the duct body and substantially parallel to an interior surface of the duct body. A first acoustic absorbing material may be positioned between the duct body and the first perforated wall. A silencer element may extend axially through the duct body, the silencer element including a second perforated wall having a second acoustic absorbing material adjacent thereto.

Description

technical field [0001] The present disclosure relates generally to sound attenuation, and more particularly to a muffler duct having a muffler duct body and a muffler element extending therethrough. Background technique [0002] Noise reduction systems are used in many types of industrial machinery, such as turbines, to reduce the sound impact on the surrounding area. For example, in gas turbine systems, noise reduction systems may be used in the turbine inlet duct, gas turbine enclosure, and barrier walls. Traditionally, muffler panels and acoustically treated walls have been used in noisy areas in order to achieve the required sound reduction requirements. One mechanism to reduce the impact of sound consists in treating the walls with sound absorbing material. Another mechanism is to place muffler panels in areas where noise reduction is desired, such as the working fluid flow path in the intake system duct, to prevent noise from escaping. [0003] With regard to the tu...
