Boiler | Engaged in Thermodynamics

The majority of the boilers in the late 1800s and early 1900s were fire tube boilers which operated like water tube boilers except that the hot combustion gases used to heat the water were passed through tubes submerged in water within the boiler. The boilers exploded because they could not be safely pressurized with the existing technology.

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 (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Industrial Combustion Boilers - IEA-ETSAP

In water-tube boilers, the boiling water flows inside tubes and hot combustion gases flow on the shell side. Fire-tube boilers were first developed in the 18th century. In the current designs, the technology of choice is the water-tube design which is more suited to high-pressure steam generation as small tubes can withstand high pressure

Steam Generator Boiler in Customised Design.

Unlike the conventional fire-tube steam boiler (fire/smoke tube boiler), the water in the steam generator boiler contains a very small amount of water and steam (equal the volume inside the pressure vessel i.e. inside the tube).

Water-tube boiler - Wikipedia

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes
