Fire-tube boiler - Wikipedia
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low

Soot & Scale Affects Boiler Performance | Goodway
In a watertube boiler, water runs through tubes that are surrounded by the heating source. Because the water is heated to very high temperatures in this type of boiler, the solids in the water tend to accumulate quickly on the tubes' inside surfaces, causing the same heat transfer problem and related cost increases that occurs in firetube boilers.
