Fusible plug - Wikipedia

A fusible plug operates as a safety valve when dangerous temperatures, rather than dangerous pressures, are reached in a closed vessel. In steam engines the fusible plug is screwed into the crown sheet (the top plate) of the firebox, typically extending about an inch (25mm) into the water space above it.Its purpose is to act as a last-resort safety device in the event of the water level

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.

Safety Valve Installation | Spirax Sarco

This can be achieved by installing the safety valve above the steam pipe as shown in Figure 9.5.1. Where safety valves are installed below the pipe, steam will condense, fill the pipe and wet the upstream side of the safety valve seat. This type of installation is not recommended but is shown in Figure 9.5.2 for reference purposes.

The set pressure of the PORV is lower than that of the spring-loaded safety valve to prevent or reduce the number of lifts of the safety valve, thus extending their life. The PORV is available either non-stamped or with the "V" stamp. The "V" stamped PORV has been flow certified by the National Board of Boiler and Pressure Vessel
