Water Tube Boiler – Definition, Components, Working …

Jan 24, 2019· A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. This is because of condensed tangential pressure on tubes which is known as hoop stress.

Water Tube Boiler – Types, Working, Construction …

Aug 28, 2019· Water Tube Boiler is a high-pressure boiler that operates at a pressure of about 165 bar. Basically, in this boiler, water will be flown inside the tubes surrounded by flue gases. More steam is generated by using this boiler so, the overall efficiency of the boiler is high. The water Tube boiler is shown in the figure below.

How a Water Tube Boiler Works | Miura America

Apr 06, 2020· In a conventional fire tube boiler, the hot gases move from the firebox into heating tubes immersed by water in the tank. As the walls of the tubes are heated by the gas, the heat transfers into the water, eventually converting the hot water to steam. While this design is quite common, it is also fairly inefficient for a couple of reasons.

Fire-tube boiler – Wikipedia

Nov 13, 2004· A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
