When you hold the temperature at the boiling point long enough, the water continues to vaporize until the pan is dry. A point to remember is that the temperature of water does not increase beyond the boiling point. Even if you add more heat after the water starts to boil, the water cannot get any hotter as long as it remains at the same pressure.
Boiler Mountings. Boiler mountings are components used for ensuring the safety of boiler operation. These are generally mounted on the surface of the boiler. Control fluid parameters at the inside of the boiler shell. The mountings are the essential part of a boiler, without which boiler operation is impossible.

The boiler accessories are the devices, which form an integral part of
The steam generated by a boiler is generally wet or at most dry saturated. Super heater is used to increase the temperature of steam above its saturation point, since superheating result in the increase in efficiency and economy of the steam plant.
Definition: Definition A boiler or steam generator is a device used to create steam by applying heat energy to water Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers worked at low to medium pressure (1–300 psi /0.069–20.684 bar ; 6.895–2,068.427 kPa ) but, at pressures above this, it is more usual to speak of a steam
Here is a list of twelve major mountings and accessories of a boiler. 1. Dead Weight Safety Valve: As the name implies, this valve is used to assure safe working of the boiler.
