What counts as a gas turbine silencer and why is it important?
Gas turbines are commonly used in power generation, cogeneration, oil and gas processing, and in a number of other industrial applications since they are able to produce a high power output with a relatively small installation. The same high-speed combustion and exhaust processes which make gas turbines efficient also result in a large amount of acoustic energy; exhaust noise will have an impact on the workers, on the neighbouring communities, on the equipment areas, and on the general conditions of plant operation if adequate noise-control equipment is not provided. A gas turbine silencer is an acoustic device which has been designed and installed in the exhaust system of a gas turbine in order to reduce the noise caused by the high-velocity exhaust gases while at the same time allowing the gases to flow efficiently through the system. Silencers that are properly designed assist in controlling excessive noise without either unnecessarily restricting the exhaust flow or compromising t...
