Feb 19, 2015 · The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy and produce steam. Here are a few key differences between the two: Firetube Boilers: - compact construction.

Mar 16, 2017 · How A Water Tube Boiler Works. A water tube boiler runs off of water tubes that are heated externally by fire. The tubes connect to a steam drum and a mud drum, and steam is produced in the upper drum. The water in the tubes creates steam directly, instead of tubes heating water as is the case in a fire tube boiler.

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.

Aug 08, 2009 · The answer is in the name. Boilers are made with a "tube - in - shell" construction, and the name implies what is in the tube. In a water tube boiler, the water circulates through the tubes, and the burner is usually under them. Most of the time, the "shell" of this style of boiler would not be watertight. A fire tube boiler has a watertight outer jacket with tubes through the center of it.
