Acoustic Silencers, Enclosures and Exhaust Systems

Acoustically speaking, the Gas Turbine is not environmentally friendly.  AAF provides 'tuned' silencers and enclosures to meet the near field and far field conditions.  Thermal shock caused exhaust temperatures at up to 650°C coupled with turbulent air flows, make the design and construction of silencers critical to the long-term performance of power generation train. The AAF MEX (Modular Exhaust Silencer) is a splitter type silencer which allows the air to pass over all four sides of the acoustic attenuators (see photo).  This feature not only provides a smaller cross-sectioned area and shorter length than conventional exhaust silencers, its construction exposes all structural surfaces to achieve uniform thermal expansion. Degradation in acoustic attenuation is most prevalent in turbo machinery that has run through cyclic start and stop conditions. Changing local conditions such as the addition of extra machinery or the building of new residential areas may mean that noise attenuation has to be increased. AAF can provide long life solutions targeted to suit the most arduous of environmental conditions.acoustic enclosures can be supplied, which can retain hydrocarbon fires for up to 60 minutes. Enclosure ventilation systems can maintain acceptable air temperature while preventing noise breakout. For additional information on all of our Gas Turbine Products, contact us at 888-223-3596 or at .
