Common safety valve silencers
Common safety valve silencers
(OP)
For years I have always taken it as read that each safety valve should have its own silencer. But these days there seems to be a trend towards routing several safety valve vents to a common silencer. Even those from the drum and superheater outlets.
Does anyone have opinions on this trend.

Talk with some of the silencer vendors and tell us what they say...
Try these people first.....

I do not think it can be done.....silencers are designed, built and certified to reduce noise to a certified level AT A PARTICULAR FLOW !!!
You are asking for a device that would operate at a multiple of flow rates...
My opinion only

Actual functional concern is if one line has a leaking valve, then line will fill with condensate (drains commonly clog). In a safety blow situation or if connected to a start-up vent, then you are slugging that water column at high velocity up into the silencer. Either over-size drains or keep as individual.

This can be achieved with diffuser pipes.

collecting pipe
silencer with two inlet diffuser pipes
