: Hi Steamer
: The steam line from the boiler house to the accumulator is 6 inch, reducing to 4 inch at the inlet to the accumulator sparge pipe.
: The present safety valve is a 3 inch inlet/3 inch outlet double spring safety valve (2 inch valve seats)
: Hi Dillon
: What is the size of the pipe that connects to accumulator?
: What is the size of the current safety valve?
: It seems that if you have a 9000 lb/hr accumulator you should have an inlet capacity of less than this value. By definition a steam accumulator as an inlet equal or lower than the outlet, but...
: In any case equalizing the pressure of boilers with the accumulator can be a safe thing to do. The difference in specific volume at this pressure
: is not significant so there is no losses, unless you have a steam turbine were 40 psi can affect dramatically the performance.
: You can learn more about steam accumulators on http://www.spiraxsarco.com/learn/
