The main difference between fire tube and water tube is that in fire tube boiler the flue gases flow in the tubes and water flows from the shell and in water tube boiler, water flows from the tubes and the flue gases from the shell or passes over the tubes. Water Tube boiler has more advantage due to main following differences.
The difference between fire tube boiler and water tube boiler can be done on various points. These points includes types of fluid flows within the tubes, steam generation rate, floor area required for the steam generation, transportation, efficiency, fluctuating loads, operating cost etc. the knowledge of the difference about these two boiler is very crucial.
Smoke type boilers as name suggests have smoke or heat flowing through inside the tubes and the water surrounds these tubes. Smoke tube boilers are generally used where there is less demand of superheated steam. Composite boilers that are used on ships are

The principle in the fire-tube steam boilers, is that from the surface of a large volume of feed water, steam is evaporated. This boiling process is heated by the wall of the combustion chamber (the radiant part) and by the exhaust gasses passing through a bundle of so-called fire-tubes or smoke-tubes forming the the convection part of the boiler.
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:
Fire tube boilers are a lower cost alternative to water tube boilers and are often used for smaller industrial facilities with lower operating pressures. The main advantages of a fire tube boiler are its simple construction, compact size and the ability to easily meet rapid fluctuations in steam demand.

Mar 27, 2010 · Fire-tube boiler
A fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or more tubes running through a sealed container of water. The heat energy from the gases passes through the sides of the tubes by thermal conduction, heating the water and ultimately creating steam.
Merits of Water Tube Boiler over Fire Tube Boiler: Generation of steam is much quicker due to the small ratio of water content to steam content. This also helps in reaching the steaming temperature in short time. Its evaporative capacity is considerably larger, and
