Fire-tube Boiler

 

a cylindrical steam boiler with fire tubes extending inside the water area of the boiler from one end plate to the other. A fire-tube boiler may have one or two fire tubes, sometimes more.

Fire-tube boilers appeared in the early 19th century as a result of efforts to increase the steam-producing capacity of simple cylindrical boilers while preserving their overall dimensions by developing their internal heating surfaces. Be-cause of their extremely large size and the significant consumption of metal in their construction, fire-tube boilers have not been made in the USSR since 1951; they have been re-placed by more advanced models.

Water-tube boilers are more efficient than fire-tube boilers. Water tube boilers have larger boiler capacities, higher pressure levels, and the ability to provide high steam temperatures of up to 650 AC.
