What is this?

This thing is on a steam boiler that does not have a Hartford Loop nor return lines. from looking on wall, realized it is a counter flow system. If I decide to take the job, I will do it the Steve Gronsky way, which I saw on the wall.

Looks like an anti-surge tank which dries the steam. Last time I looked, a few small places still made these.

IIRC, it could be a water/steam separator.

Have seen something like that here on the wall some time ago.

Our local supplier used to push them every time we purchased a Weil McLain or Union Steam all the time. Never actually installed one but have seen a few. In my opinion, pipe the boilers correctly and there is no need for a separator.

I've cut a few out Sears and 'Monkey-Wards" made some thing similar.  As Scott said..unnecessary.   mad Dog

They do work. It contains a dip tube for the steam. The wide space in the road seriously slows the steam velocity as it leaves the boiler. There’s little carryover.

I'm sure, but wouldn't a good full port drop header do the same, Dr Holohan? (Professor Emeritus of The Steam and all Hydronics).  If I cut it out, its at Suffolk County Community College Heating Museum where all my Larger relics have their final resting place.   I know Prof. Eugene runs things out in California.  Who in charge there now Dan?  I have a few "new" older items I WILL NEVER junk...

It does what a drop-header does, Matt, and at less expense. These devices are from the '80s and they helped when the steam boilers were really hot-water boilers, trimmed for steam usage. The steam velocity of those boilers was much too high and the separator slowed the steam significantly. They were more popular in New England than in NY.

I don't have any contacts at Suffolk Community College. I saw Eugene at AHR. He's looking good.

I believe I saw these in Dan's book, TLAOSH

DanHolohan

Yes

Dano.  I'm going to reach out to Suffolk CC and pay a visit to review what they have on display and reestablish a connection with them and see if they want more artifacts  mad Dog

Nice! Thanks.

Thanks for the feed back guys. I knew I would get the answer on this site! I sent a photo to a few of my suppliers, but no one could tell me what it was. Thank you Mr. Dan Holohan for your class, books and articles which have helped our little outfit do steam better.

DanHolohan

I'm glad I was able to help. Thanks!

Since the carry over happens in the boiler where it gets pulled into the narrow tapping, that would mean that water is entering the device.

Where does this water drain back out from the device?

DanHolohan

The globe is hollow, except for a dip tube that extends about halfway in from the top. The carryover water falls right back into the boiler as the steam enters the dip tube and heads up into the system. It's very simple. Devices such as this one have been around for more than 100 years. They reappeared during the '80s because the steam boilers of that time were really hot-water boilers, trimmed for steam.

I wish someone had a patent drawing or something.
I'm having a hard time picturing it.

I didn't even notice it among all of the other posts, I'm sorry Scott.
That's exactly what I needed to see.

Steam drums and separators are a good idea. I believe some systems used flash tanks & separators in returns as well.

Think it's cheaper than a drop header?
