Safety Valve For Gas Boiler

Top Ten Boiler and Combustion Safety Issues to Avoid

Gas pressure regulator (PRV) - the purpose is to maintain the pilot fuel at a constant pressure as recommended by the burner manufacturer. Safety shut-off valve (SSOV) - automatically opens and shuts off fuel supply to the pilot burner. Testing of the fuel firing apparatus, including the flame safeguard system, is relatively easy.

Boiler Safety - OSHA

First developed for use on early steam boilers as operating without them would cause an explosion unless carefully operated. Modern burner ovens now feature a gas safety valve to prevent an explosion when unlit. Unless ignited by an electric glow bar, pilot flame or electric spark with a gas supply, the valve will remain closed.

Safety Valves in Boiler System - Bright Hub Engineering

Safety valve is used to guard the boiler against the excessive high pressure of steam inside the drum. If the pressure of steam in the boiler drum exceeds the working pressure then the safety valve allows blow-off the excess quantity of steam to atmosphere. Thus the pressure of steam in the drum falls. The escape of steam makes a audio noise to

Safety valves are commonly tested by lifting the safety valve try lever.. 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.
