ƒA water-tube boiler is one in which the products of combustion pass around the outside and heat tubes containing the water. ƒThe water tube diameter is much smaller than the shell diameter of a fire-tube boiler, so much higher pressures can be obtained, well over 2000 psi.

The move to water-tube boilers had already begun, with designs such as the Babcock & Wilcox or the Belleville. The three-drum arrangement was lighter and more compact for the same power. The new generation of "small-tube" water-tube boilers used water-tubes of around 2 inches (5 cm) diameter, compared to older designs of 3 or 4 inches.

Boiler Guide: Firetube vs. Watertube – What’s the Differenc

If the boiler is a steam boiler, the natural pressure created by the steam forces the steam to flow through the piping. Firetube Boiler. Instead of having vertical metal tubes filled with water, a firetube boiler has horizontal tubes filled with heat from the burner flames. These tubes run through the water vessel and heat the water via convection.

How a Water Tube Boiler Works | Miura Ameri

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.
