16 Difference Between Fire Tube Boiler And Water Tube …

Water tube boiler occupies a less floor area when compared to a fire-tube boiler that requires a large floor area. Water-tube boilers are lighter in weight and therefore transportation is also not tedious. Fire tube boilers on the contrary are heavy in weight and therefore they cause a lot of challenges to transport.

Water-tube boiler - Wikipedia

Water-tube boiler. 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. In smaller boilers, additional generating tubes are separate in
