There have been a vast number of designs of, particularly towards the end of the 19th century when the technology was evolving rapidly. Detail kusen pintu dan jendela autocad. A great many of these took the names of their originators or primary manufacturers, rather than a more descriptive name. Some large manufacturers also made boilers of several types.

Accordingly, it is difficult to identify their technical aspects from merely their name. This list presents these known, notable names and a brief description of their main characteristics.

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, where steam was used as heating for the cars being pulled. With the advent of, these steam boilers were phased out, often being replaced with concrete weights.

The flues were round, rectangular or arched and usually long and labyrinthine. •: a rarely used boiler for steam locomotives that combined a conventional fire-tube boiler barrel with a water-tube firebox.
