Boiler Feed Water Tank
Boiler Feed Water Tank
(OP)
I have existing boiler (4MMBtu/hr), and the condensate return from the Process side is going directly to Boiler Feed Water Tank. Plant is not in use since last couple of years and client is planning to start the plant. It is a small boiler so it doesnt have deaerator.
The concern is from the process side (from steam traps) condensate header is going directly to Boiler Feed Water Tank, so Tank is also acting as a Flash vessel.
The Boiler Feed Water Tank is Atmospheric and it has vent on it. I am not sure if the Boiler Feed Water Tank has to be pressure vessel.
Thanks in advance for your feedback.

If it is fitted with a nameplate and there is mention of ASME VIII or similar, then is a pressure vessel. Otherwise is not.

Be careful if there is a valve in the vent line! If there is a valve (even if the tank operates if the valve opened) I would categorize the tank as a pressure vessel.
I also suggest checking the pump for cavitation.

RE: Boiler Feed Water Tank
Since the system has not been used for a couple of years, my only question would be-How was the boiler "laid-up"? Hopefully it was in dry lay-up packed with desiccant for the last couple of years, otherwise it could be very corroded on the inside.
A thorough inspection is in order!
