near boiler piping - steam - DVW

bob young

if you should ever meet up with any real nyc steamfitters and discuss piping techniques et al you might be surprised and possibly eat your words . working on hi-pressure manhattan systems and complicated hi-rise buildings is not a job for the unqualified. if you are an expert on nyc systems ,i have found i can adapt those skills and work pretty much anywhere.

Picture worth a word or two

So the saga continues - I didn't like the near boiler piping when I saw it and didn't know why - but a little voice said - that don't look right.

So - I've invested in some GREAT books - from the HeatingHelp.com book store, and THERE IT IS......the bull headed tee.

It also explains why I was struggling to figure out why it took so long to fill the boilers. The boiler feed pumps are close by and there are zone valves on each boiler that I can watch open and close.

Doing the math and timing the opening and closing of the zone valves didn't jive with the head pressure of the boiler feed pump and the operating pressure of the boiler.

The boiler should fill in 9-11 seconds and it was taking as long as 40 second for the zone valve to close.

The steam is leaving the boiler, taking water along with it (wet steam) and how did I figure that out?

Measure the condensate drip at the end of the steam header - The condensate is pouring out of the F&T trap - the header was hot and up to pressure.

Cool stuff.

Thanks to everyone who offered their two cents!

The trap in the picture

Is in the wrong place too - that's supposed to be an overflow trap.

It cracks me up when you get an earful from the "steam fitters" in NYC, only to find out that's what all they are.

"connecters of this thing to that thing."
