Combined Cycle
Custom silencers, diffusers and shrouds for combined cycle gas and steam turbine noise control challenges.
Noise Control Solutions for COmbined Cycle Power Plants
Combined cycle power plants use sophisticated dual-turbine systems that create complex acoustic challenges. These facilities require comprehensive noise control to mitigate the diverse sound sources generated by both gas turbine and steam turbine operations, along with their supporting systems.
Combined cycle plants generate noise from multiple interconnected systems that operate simultaneously, and noise increases significantly during startup. Unmitigated startup noise can reach levels 20 dB higher than baseload operation because of bypass operations, steam venting and rapid load changes.

How Burgess-Manning Controls combined Cycle Noise
Flue gas silencers are custom designed for exhaust and HRSG systems, whether mounted in a silencer duct or a hot or cold stack. Inline diffusers and spargers handle steam expansion from turbine bypass upstream of the condenser and commissioning silencers control the high-pressure steam blows used to clean piping before startup of a new plant.
Acoustic shrouds are modular and can connect directly to the HRSG or stand alone, treating radiating surfaces while allowing natural ventilation to prevent heat buildup. Filter silencers, acoustic enclosures and ventilation systems complete the treatment around each gas turbine.
