Taichang Power company, Taiwan
(World’s Largest Vent Silencer)
A Blow Off Silencer will be normally a vent silencer installed in discharge by pass line of
compressors. In the case of discharge silencer the air / gas enters through the diffuser and
passes through the straight air path between annular acoustic cylinder and escapes into the
atmosphere. Normally such vent silencer is provided with a weather cowl.

Vent Silencer with 5 Tangential Nozzles Vent Silencer for SIEMENS
UDHE Germany
Both Suction and Discharge Silencers shall be supplied either in circular or rectangular
construction for fan/ blower and turbo blowers. The rectangular silencer shall be of
absorptive type installed either at suction side or at discharge side of fan/ blower. The
internals of the silencer comprises a series of acoustic splitter elements arranged in parallel
inside the rectangular steel casing. This would ensure the flow of air/gases through the
rectangular air gap between acoustics splitters and thus offering a minimum pressure drop.
The leading and trailing edge of the acoustic splitters will be designed aerodynamically to
offer minimum resistance to the flow medium.

within 75 dBA. The chamber was provided with forced ventilation system consisting of
centrifugal blowers and the exhaust ducted to out side. The acoustic chamber is provided
with automatic sliding doors at both ends to facilitate the movement of cars in and out of the
chamber. After installing the system, a noise survey was conducted and the noise level was
found to be within the specified limits.

It is intimated that Acoustic system of CCP-2 has been commissioned on 03-05-95 and
taken over by us on 26-5-95. The system installed as a whole is working satisfactorily since
then. It was supposed to bring down the noise level within 85dba as per our Tender
specification. After testing by Environment control department on 03-05-95 its noise level
was below 85dba. Also in many places noise level was found 80dba and average so this
system is finally acceptable to us.
