What Parts and function of safety valve of boiler?
If the pressure in a steam boiler exceeds a set limit, a safety
valve is provided that will open to relieve the pressure. This
prevents a boiler explosion. When the pressure is being relieved in
this way, very hot steam will be release from the valve. The hot
steam is extremely dangerous to people, therefore a discharge is
provided. This is a pipe or other means of directing the hot steam
to a release point outside, away from where people are likely to
be.
