The difference between fire tube boiler and water tube boiler can be done on various points. These points include 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 boilers is very crucial.
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.

An Introduction to Treatment of Steam Boiler Water
Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence. Water-tube boilers tend to be higher rated, perhaps over 1 000 tonnes/h of steam.
The structure of heavy oil fired water tube boiler is arranged as drum longitudinal type "D" shape, it's quickly assembled boiler with water tubes, has the characteristics of high steam quality, sufficient output, and high thermal efficiency (97%), etc. T
Boiler: A Boiler is a closed vessel in which steams are generated (Water to steam) with the help of coal-burning or other fuel substances. Basically, There are two types of Boiler.Fire Tube Boiler Water Tube Boiler Fire Tube Boiler: The fire-tube boiler is the boiler in which fire (hot flue gases) is inside the tube and water is surrounded by them.
Water Tube Boiler: Types, Parts, Working Principles | Linquip
Optimal water tube arrangement and burner with high combustion efficiency deliver high boiler efficiency. The extremely broad turn-down ratio makes it possible to save fuel consumption during actual operation. We design grid-shaped water tube arrangement. With
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.
