Boiler Machine (steam generator)

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.

An industrial boiler, originally used for supplying steam to a stasionary steam engine

A boiler or steam generator is used wherever a source of steam is required. The form and size depends on the application: mobile steam engines such as steam liocomotives, portable engines and steam-powered road vehicles typically use a smaller boiler that forms an integral part of the vehicle; stasionary steam engines, industrial installations and power stations will usually have a larger separate steam generating facility connected to the point-of-use by piping. A notable exception is the steam-powered fireless locomotive, where separately-generated steam is transferred to a receiver (tank) on the locomotive.
