In Reply to: Saftey valve question posted by Bill on February 14, 2007 at 20:24:00:
: 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
Thanks for the replys. The MAWP is 150 and all 3 saftey valves are set at 150. Each one is a different size and they are lined up next to each other. We have another boiler a CB 350 hp it has 2 saftey valves a large one and a smaller one both are set at 150 and the MAWP is 150. Both boilers have a pressuretrol that shuts the boiler off at 125psi.
