It is vital to keep the silencers in a good condition to get a good level of sound reduction to protect the workers from the high level of sound as per international standard of noise regulations.
passive and reactive elements are commonly used to reduce the noise propagating from the turbine exhaust stack.
Silencers normally contain one or more passages, which are lined with sound absorbing materials incorporated in structures that protect them from erosion from airflow.
Due to long period of continuous operation under sever conditions such as high temperature, very high gas flow velocity the silencers can be damaged and the infill absorbing material fibers immigrate from the silencers.
Modern Insulation Industries Co. (MIIC) have a good experience in silencers repair and replacement with deep attention to all details to allow expansion and construction to happen without any damages.
