Boiler Silencers
From Acoustic Treatment
Double-chamber resonator: This silencer is formed by assembling two volumes inside a section of the smoke flue (exhaust or chimney) through which all smoke flows. The transversal section of these chambers is greater than the size of the flue, hence the name «expansion chamber». Gas inlets and outlets of these silencers can be axial or radial.

Other Process
Quarter wave resonator
The quarter wave resonator is a silencer made of a closed bend at one end (90° elbow with bottom). It is characterised by the fact that no flow runs through it.
This silencer is by definition highly selective, i.e. it attenuates noise within a very narrow frequency range.
The distance of its location in the flue is very important and must be determined very precisely to obtain good results. It is used for an emergent noise at a carefully defined frequency
