Mark .. Thank you and I agree. But I had a co-worker argue with me ..that by evaporating the moisture, more oxygen was liberated and less air would be needed. I was asking this question to make sure I wasn't off base
We are looking at doing that ..but we're talking 6 safety valves.. so I was looking at the possibility of putting 2 valves on the header. I knew I could "safety" the header to protect the downstream equipment ..but I wasn't sure how the code handled the different pressure boilers.
All the boilers will operate at 125 psi ... but two boilers are designed for 250 psi with appropriate safety valves ..one boiler is designed for 150 psi with it's valves set at 150 psi
Where in the ASME code can I find : when there are 2 or more high pressure boilers connected to a common header and the boilers are of different design pressures that a steam header safety valve(s) must be installed
