Noise Control Solutions for Waste-to-Energy Plants

Waste-to-energy plants burn municipal solid waste or biomass to generate steam, giving them a combustion and thermal noise profile like conventional thermal plants despite their renewable classification. Many are built near the communities that supply their waste, so noise from boilers, fans, steam systems and material handling must be controlled to meet site-boundary limits.

Noise Sources in Waste-to-energy Plants

  • Boiler and Steam Turbine Systems: continuous thermal and rotating equipment noise.
  • Flue Gas Path and Stack: exhaust gas noise through ducts, the flue gas path and the stack.
  • Induced and Forced Draft Fans: large fans with strong tonal noise at inlets, outlets and in ductwork.
  • Ash Handling Equipment: conveyors, crushers and related mechanical noise.
  • Steam Venting and Bypass: high-velocity steam release during startup, trips and bypass operation.

How Burgess-Manning Controls Waste-to-energy Noise

Flue gas silencers are custom designed to reduce exhaust and stack noise to meet environmental standards, while in-line silencers and rectangular and circular attenuators treat piping, ducting and fan noise. Inline diffusers and spargers handle steam expansion from turbine bypass, a service common to biomass and combined cycle plants, and vent silencers treat steam and gas discharge.

Commissioning silencers control the noise of steam blows used to clean piping before a new plant starts up, and acoustic enclosures and noise barriers contain noise from machinery and ash handling areas.
