The National Board of Boiler and Pressure Vessel Inspectors

Steam boilers require a device which senses steam pressure and cycles the burner or other source of heat in order to maintain a consistent, predetermined operating pressure. A second device is used to prevent the boiler from exceeding the maximum allowable working pressure (MAWP) indicated on the boiler nameplate.

What is a Maximum Allowable Working Pressure (MAWP

Corrosionpedia explains Maximum Allowable Working Pressure (MAWP) The boiling temperature of a liquid increases with pressure and decreases when pressure decreases. A crack in a boiler would lead to the pressure dropping to the atmospheric one. This would cause water to boil at 212°F (100°C), which can cause superheating (heating water past its boiling point), which can in turn lead to an

Difference Between Low- and High-Pressure Boilers | Hunker

A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.
