I'm looking into ASME book and see nothing about your ???.
Citation: "Each boiler shell have at least one safety or safety relief valve...and if it has more than 500 sq ft......it shell have two or more ..."
" ...Minimum required relieving capacityof ... valves for all types of boilers shall be no less than the max. designed steaming capacity..."
: I have a CB 600 hp fire tube boiler. It has 3 saftey valves on top all are set to pop at 150#. Why is each one a different size? One is 6000# per hr, one is 8000# per hr , and one is 10000# per hr. The total is 24000# why not have 3 8000# valves? Is there some reason for this? Thanks Bill
