    trap

    Looks like an old school F&T trap  with an external T part,  hard to say, describe   where the piping is coming from and going to

    I think

    that's a "float trap/air eliminator" as described in chapter 15 of Lost Art. It is the only place where air is vented from the system.

    Is this device on the dry return near the boiler?

    I agree.

    It's a central air eliminator. The float keeps the boiler water from flowing out the vent hole. It's not a steam trap.

    Looking at it

    Sideways I believe and my first thought was also some kind of vent.

    Take a temp. reading from inlet to outlet, if the temp is the same this would indicate a problem with the trap, it can be replaced with a Hoffman F&T trap. there would be extensive repiping

    I'm glad you asked.

    A trap in that spot would have hurt.

    Thank you for the info, now for 64 thousand dollar question, what can replace it.

    Is it broken?

    If so, a high-capacity main vent. But if it still vents I'd leave it.
