Boiler Operation with Low Furnace Pressure

Low furnace pressure if not handled by the boiler operator at the right time can lead to furnace implosion. Each large balanced draft boiler is designed for a particular implosion pressure. Like the high furnace pressure withstanding capability the balanced draft furnaces have a good implosion pressure withstanding capability. Implosion is large pressure acting on the walls of the furnace from

Boiler (power generation) - Wikipedia

2019-10-30 · 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.
