Safety Valve Capacities in Low Pressure Steam Systems

The size of the safety valve depends primarily on the maximum boiler output and the operation pressure of the system. The safety valve shall as minimum have the evacuation capacity of all the vapor the boiler can produce running at full power at working (or certification) pressure.

Your guide to safer boiler operation

– The safety valve is the most important valve on the boiler. Safety valves prevent dangerous over pressurization of the boiler. Safety valves are installed in case there is failure of pressure controls or other devices designed to control the firing rate. All safety valves should be kept free of debris by testing the safety valve regularly.

Difference Between Safety Valve and Relief Valve -

we know a boiler has both relief valve as well as safety valve. Suppose we have a boiler whose working pressure is 6 Bar. Now the set point for pressure relief valve is 6 Bar so that it whenever the pressure inside boiler increases beyond 6 Bar the relief valve opens.

Boiler Safety

With the boiler pressure at a minimum of 75% of the safety valve set pressure, the safety valve try lever is lifted to wide open position. Steam is discharged for 5 sec to 10 sec. The try lever is released, and the disk should snap to the closed position against the valve seat. Malfunctioning safety valves must be replaced as soon as possible.
