Abstract
A silencer device is installed into the discharge pipe of a centrifugal compressor by first installing a channel shaped frame in the discharge pipe and then sliding the silencer device into the frame to be contained for operational use. The orientation and placement of the frame and its contained silencer device is parallel with the direction of flow to thereby reduce the resulting pressure drop, and it is placed near a turn in the discharge pipe such that the sound will tend to be reflected from the discharge pipe to cause multiple passes through the silencer device and thereby enhance its absorptive performance. The absorptive material within the silencer device is protected from erosion by a surrounding cloth bag composed of a fine weave Nomex material.
