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.

3.Two types of high pressure water tube boilers are specified, flex tube and D-type. The two boiler types are significantly different, and only one of the two types should typically be specified if all new boilers in a given project are similar. 4.Flex tube boilers: a)Primarily for non-critical service firing gas fuel and with stable steam demands.

The water-tube boiler may just result in a tube leak, which can be easily contained. Conclusion. Water-tube and fire-tube boilers are complete opposites in terms of the location of the water relative to the hot gases resulting in water-tubes boilers being inherently more efficient in terms of the heat transfer.

Industrial water tube boilers have a much more efficient design that saves both space and energy. that flows throughout the boiler. With the water tube design, the water is surrounded by heated gases rather than the other way around. The hot gas moves from the firebox into the boiler's main chamber.

Fuel sources include natural gas, low-pressure propane, No. 2 oil, coal and other fuels. Tubes: In watertube boilers, the metal tubes situated inside the boiler contain water and are externally heated. In firetube boilers, heated gas passes through one or more tubes, heating water surrounding the tubes.
