    A "Scotch" marine boiler (or simply Scotch boiler) is a design of steam boiler best known for its use on ships. Sectional diagram of a "wet back" boiler. The general layout is that of a squat horizontal cylinder. One or more large cylindrical furnaces are in the lower part of the boiler shell. Above this are many small-diameter fire-tubes ...

    However, the furnace in a gunboat boiler has no opening at the bottom of the furnace to allow dumping of ash; the furnace is completely water-cooled, similar to a Scotch boiler furnace. These boilers were used in early torpedo boats and gunboats, having low height for protection from enemy gunfire. Galloway boiler

  4. Fire-tube boiler - Wikipedia

    en.wikipedia.org/wiki/Fire-tube_boiler

    This firebox has an open base to provide a large grate area and often extends beyond the cylindrical barrel to form a rectangular or tapered enclosure. The horizontal fire-tube boiler is also typical of marine applications, using the Scotch boiler; thus, these boilers are commonly referred to as "scotch-marine" or "marine" type boilers. [2]

    Also known as Rectangular boilers and Wagon-top boilers. The Martin or Cochrane boiler was a direct evolution of the Flued one, with adding vertical water tubes into the large fire passages, later ones had horizontal water return-tubes like on the Scotch boiler.

    They operated with a stroke of 69 in (1,800 mm). Steam was raised from twelve double-end Scotch boilers, each measuring 18 ft (5.5 m) in diameter and having eight furnaces. There was also one single-ended boiler for auxiliary machinery and one smaller donkey boiler. Boiler pressure was 165 psi (1,140 kPa), enabling the engines to produce 31,000 ...

  7. Launch-type boiler - Wikipedia

    en.wikipedia.org/wiki/Launch-type_boiler

    The boiler has similarities with both the locomotive boiler (the multiple small fire-tubes), and the Scotch marine boiler (the short cylindrical furnace). As a fire-tube boiler it has generous heating area and so is an effective steamer. Firebox construction is also simpler, thus cheaper, than for the locomotive firebox.

    Wrought iron could not provide the strength for the higher pressures. Steel became available in larger quantities in the 1870s, but the quality was variable. The overall design of boilers was improved in the early 1860s, with the Scotch-type boilers – but at that date these still ran at the lower pressures that were then current. [28]: 106-111
