Velox Boiler Pressure

Boiler (power generation) | Tractor & Construction

2014-4-4 · 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 (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 generator.
