Safety Valve Capacities in High Pressure Steam Systems

The safety valve must as minimum have the evacuation capacity of all the vapor the boiler can produce running at full power at the working (or certification) pressure. for a higher pressure the steam is compressed and requires less volume and the size of the valve can be reduced. for a lower pressure the steam is expanded and requires more
