When to use a deaerator versus heated feed tank versus a feed tank with no heat
When to use a deaerator versus heated feed tank versus a feed tank with no heat
(OP)
Hi all,
I am looking for something that I can cite as a "governing authority" or at least "industry standard" on when to use a deaerator versus a feed tank with a steam bundle or sparger, versus no heat in the feed tank. I understand the need and benefit of heat to remove oxygen, so please don't take this thread down that road. I also understand that the amount of fresh makeup water is a large contributing factor to the amount of oxygen need to be removed. I'm not looking for an explanation of the chemistry, but rather a good reference.
Is there a code or some other official reference that can be used to argue the point one way or the other? I'm trying to make the case to a client, but stating that "... In my experience..." isn't a strong argument.
I'm looking something to cite on when I absolutely should deaerate versus heated tank versus no heat in the tank. I know it's not a simple 1-2-3 scenario, but again I can't find anything that I would consider good guideline on this.
Thanks,
Steve

Good practice to preserve the life of the boiler and save energy would be to use dearator.

I believe that there are some US military standards regarding boiler room accessories. .....
A Deaerator is always required to extend boiler life.

As the reachable O2 levels will be different, depending on the type of deaerator or tank you choose to use this could be a guide.
Further you could calculate the amount and cost of oxygen scavenger you need to reach the target level with the cheaper designs and show such that the life cycle costs for the lower CAPEX alternatives are higher than for a proper deaerator.
