A small boiler may be used as an auxiliary boiler when at sea, or a donkey boiler in port. A composite auxiliary boiler does this, using waste heat from the main engines when at sea, or is separately fired when acting as a donkey boiler. Auxiliary boilers were also present in some locomotives, in particular those used in passenger rail service ...

An O-type boiler is a form of water-tube boiler. It is named, like the D-type and A-type boilers , from the approximate shape of its tubes. They are characterised by single steam and water drums vertically above each other, with curved vertical water tubes to the sides forming an overall cylindrical volume.

The Lune Valley boiler was a small oil-fired boiler, used by the Lune Valley Engineering Co. of Lancaster, England for steam launches and small steamboats. [7] [8] Each steam generator tube consisted of three turns, giving a greater heating surface for the number of pipe joints to be made. These coils were still arranged in tiers.

erosion of a boiler's plates from the internal water space, particularly where there is a step inside the shell. This was a problem for early boilers made from lapped plates rather than butted plates, and gave rise to many boiler explosions. In later years it was a problem for the non-circular water drums of Yarrow boilers. Handhole
