Flue Gas Silencer

Our Burgess-Aarding brand Flue Gas Silencer is custom-designed to reduce noise levels of exhaust and heat recovery steam generator (HRSG) systems to meet stringent environmental standards.

Whether the Flue Gas Silencer is mounted in a silencer duct, a hot or cold stack, or has to be able to operate in high flue gas velocities or elevated and fluctuating temperatures, we can provide the most effective solution in line with the gas turbine output and single cycle or bypass/HRSG design, considering basic design criteria such as:

  • Sound power level/noise output of gas turbine
  • Noise requirement of power plant requiring dynamic insertion losses of silencer
  • Pressure drop requirements
  • Dimensions of duct/stack
  • Other noise sources, e.g., burners
  • Other noise-reducing parts of the system, e.g., boiler & elbow
  • Maximum flow velocity

With years of experience and a team of expert engineers, we provide patented silencer designs with quality materials, ensuring the best acoustical performance with maximum flow velocity.
