Visualizing invisible steam video
My next installment in "dumb boiler tricks".
In this one I saw two really interesting behaviors.
- The balls create a localized zone of high pressure under the balls, then lower pressure in and above them. I believe the condensate that we see in this video is steam that condenses due to the higher pressure zone under the balls. Then that condensate gets blown upward where we can see it in the glass. Weird! It's not boiler water because my boiler water currently has 8-way in it and is noticeably purple.
- Even with the the left supply valve completely closed, and the balls pressed against the top of the sight glass, greatly limiting the area where the steam can flow, flow it did, with barely any increase in pressure (never going over 1.5" of W.C.). This goes to show how compressible the steam is—it can get through very small spaces at the flow rates and pressures of residential steam.

Thanks! There was some advantageous editing going on 😂
They are sold that way, you can search for "tri-clamp sight glass". They are used in brewing and chemistry production. I believe they are stainless steel and glass.

I know, this one was horrible, I really needed a third hand and I couldn't find my tripod

I buy the Dernord brand from their Amazon store. They are surprisingly inexpensive. With clamps and adapters this 25 mm runs around 50 bucks. I customized some of the adapters to sweat and press.
I also found two sources for glass tube. They will cut and ship up to 24" length in different diameters and wall thickness.
I have site glasses on my HP, boiler and solar to watch for air and monitor fluid quality.

Nice. I'd like to have one of those on the 3/4" copper to my expansion tank, just because I'm curious to see if the integral air separator in my cast iron boiler is working and sending air bubbles up to the expansion tank.

that’s great, Bob! That’s my favorite brand as well.
the other cool thing is included in that price you get a free union you can open with no tools.
And the 2.5” ones I have are not much more $$

It does, but you will be sleeping or at the store when it happens. So after you spend all that time and $$$ you won't see a thing unless you have Paul show up with his overwhelming patience and a camera.

After you make that expensive repair and you still have the same problem, What will you check next?

Live stream it so everyone on HH can look if they want. It would be as entertaining as this video.

it is! Line it up so the normal water line is at the 1/3 point
