Webster Return Trap question

PG · May 2006

Yes there are dry returns. The air vents through a Webster vent trap. The Webster return trap has No 0023 Type A on a brass plate in the front of it. It also has 00TR-B 1 in raised letters on the side of it. The dirt strainer (located above the return trap) has 024 on it. I am working on getting some photos on here. When the boiler has been running for some time steam comes roaring out of the top of the vent trap.

Webster return trap??????

Having a problem with a poor steam boiler replacement. There is major noise from boiler room after system has been up and running awhile. The near boiler piping has been redone. I suspect it still isn't 100%. These guys did plug an outlet on the old Webster return trap, and they plugged the side of the strainer on top of this trap. Could these be causing problems? Should I repipe them? To where?
Thank You!!!!!

Anyone else on here have an idea about the Webster return trap? I am in the business. Just don't have all the answers, and not sure about those plugs the guys put in (see my first post). Thank You!

You'd need to know

which tapping went to the steam header and which to the dry return. Obviously the one on the bottom connects to the drip from the dry return, and also handles the wet return if there are traps on the steam mains.

There were several different versions of the Webster "Type R" Vapor system which is what this is. Pics will help.

The returns in the boiler room are all wet returns. If these are not reconnected......how would it effect the system? There is definetlty a lot of noise in the boiler room.

But the system

does have dry returns, correct? How is the air vented from these? Where do they drip into the wet returns? Do the steam mains drip into the wet returns thru traps?

That means you have bad traps

somewhere out in the system. There should be no steam at all in that dry return. Follow the steam to the bad traps.

It wasn't leaking until the boiler changeout.

Find out what changed

it could be something as simple as the new boiler having a lower water line than the old one, which lowered the water level in a loop seal to the point where steam could blow thru.

Follow the steam and you'll find the trouble.

boiler changeout

Steamhead's right. If you've got steam coming out of the vent trap, you've got bad traps somewhere. Maybe the old boiler was masking the problem by running at such a low pressure (none?). Now that you've got a little pressure more steam is making it's way through the returns.

Add a new main air vent?

Good points....checking traps, and pressure, and the water level (very good chance it's lower). I know it's not the correct fix but........what about putting a Gorton #1 in the top in place of the old ball bearing gizzy to stop the steam from destroying the boiler room?

a Gorton #2 for that.
