Boiler (power generation) - Wikipedia

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 and worked at low to medium pressure (7-2,000 kPa or 1-290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Maximum allowable operating pressure - Wikipedia

Maximum Allowable Operating Pressure or MAOP is a pressure limit set, usually by a government body, which applies to compressed gas pressure vessels, pipelines, and storage tanks.For pipelines, this value is derived from Barlow's Formula, which takes into account wall thickness, diameter, allowable stress (which is a function of the material used), and a Safety factor.

The Effects of Carryover in Steam Boiler Systems

Low capacity and low pressure boilers (typically firetube boilers) primarily rely on simple gravity separation of water and steam. At higher pressures and/or high steaming rates (typically water tube boilers), it is necessary to install internal mechanical steam separating devices to provide acceptable purity steam.

Troubleshooting Steam Heating Boiler Problems

Most steam heating boiler systems are calibrated to run at very low pressures—usually ½ psi. Mineral deposits and dirty water can lead to blockages in the piping that will cause pressure to build up within the system, much like heating an empty boiler would.
