Adding nitrogen to Boiler
Adding nitrogen to Boiler
(OP)
Hi All,
In my latest position with my company, I get to deal with some hot water boilers we use to heat chemical tanks. These run around 30-40 psi at 220-280 degrees F. I was told that we add 15-30 psi nitrogen into the supply lines to prevent the water from boiling into steam in the pipes (which cavitates the pumps and rattles the pipes to death). My question is straight out this: How does the addition of nitrogen keep the water from boiling? I would think it would just be easier to run the boilers at a higher pressure.
Thank in advance for any comments

RE: Adding nitrogen to Boiler
Otherwise, how do you propose to increase the pressure?

Compositepro-So you are saying that it is just used as a pressure boost system wide, and at that point it would seem we could use Helium or Argon instead. The point being that we just happen to be using Nitrogen,is of no importance as a choice of gas. Correct?
Thank you
