What is a Boiler and How Does it Work? | RealPars

19/8/2019 · The tubes transfer the heat of the furnace through the water in the tank. Once it is heated, the steam generated is moved along downstream. Fire-tube boilers tend to be the cheapest type of boiler to produce, as they have a fairly simple construction but are typically limited for low to medium pressure applications due to the thickness of the outer shell containing the water.

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.

Plant Engineering | Maintaining boiler safety

Water that enters the boiler is vaporized to steam, leaving solids behind in the form of scale or buildup in the areas of highest heat transfer rate. A buildup of scale deposits inside boiler tubes produces an insulating layer which inhibits the ability of the water to remove heat from the tube surface.
