6 Water tube boilers Introduction As contrast to large volume boilers, in water tube boilers water/steam mixture is inside the tubes and is heated by external combustion flames and flue gases.
Large-Scale Utility Power Shortly after our establishment in 1867, Babcock & Wilcox designed the world's first installed utility boiler. B&W boilers now provide more than 300,000 MW of generating capacity in approximately 60 countries. In 1957 when B&W built the world's first commercially operated supercritical boiler, our designs were instrumental in the advancement of power generation
I Overview Boiler burners are the functional component of boilers that provide the heat input by combustion of a fossil fuel, including natural gas, with air or oxygen.
DriSteem's STS® (steam-to-steam) humidifier creates chemical-free humidification steam using boiler steam as its energy source.
These tutorials explain the principles of steam engineering and heat transfer. They also provide a comprehensive engineering best practice guide covering all aspects of steam and condensate systems; from the boiler house and steam distribution system up to the point of use; through the condensate recovery system and returning to the boiler.
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.

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
