Thanks for your help guys, Stoddard Silencers Canada came up with a quick delivery, so we are going with them. I'll try to find a copy of that "Silencing Handbook" for future reference - thanks
Thanks for those suggestions Hatch. I'm really looking to implement a permanent solution though - have access to full machine shop, ASME welders etc - I'm a pipe stress analyst by discipline so can deal with all those aspects OK. I thought to design a sparge type diffuser to max pressure drop...
Can anyone advise where I can find basic (or detailed!)design guide for steam vent silencers.
Problem is I need to deal quickly (angry local residents) with two steam relief vents which currently discharge to a common 8" uncoupled vent pipe.
One is set 22 bar, 7050kg/h, other 12 bar...
