Fire-tube boiler - The Full Wiki

Water tubes. Fire-tube boilers sometimes have water-tubes as well, to increase the heating surface. A Cornish boiler may have several water-tubes across the diameter of the flue (this is common in steam launches). A locomotive boiler with a wide firebox may have arch tubes or thermic syphons. These increase the heating surface and give additional support to the brick arch.
