There have been a vast number of designs of, particularly towards the end of the 19th century when the technology was evolving rapidly. A great many of these took the names of their originators or primary manufacturers, rather than a more descriptive name.
Marine Steam Boilers J H Milton Pdf Files. 4/3/2017 0 Comments Marine steam boilers /. Scotch marine boiler - Wikipedia. One or more large cylindrical furnaces are in the lower part of the boiler shell. Above this is a large number of small- diameter fire- tubes.
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.

annular water-tube boiler: a vertical with the tubes arranged radially, such as the with horizontal tubes, or near-vertically and conically as used by for. auxiliary boiler: An auxiliary boiler, on a, supplies steam that is not used for main propulsion, but is necessary for some part of the essential machinery. 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. Thornycroft steam wagon boiler, an with inclined tubes B Definitions Points of Interest. Babcock-Johnson boiler: early production operating at high pressures (850psi) and with ends to their furnace.: a development of the launch boiler, with an enlarged furnace. Also known in agricultural use as the 'colonial' or 'Britannia'.: an early marine.: a 'once-through'.: An early naval.: An early marine boiler with flat sides.
Owing to the flat sides, even with extensive rod stays, the boilers were only suitable for low pressures. These boilers were physically large and contained a few large flues, each heated by its own furnace. 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. There is a prominent steam drum above the boiler barrel, making it resemble a.: a variant of the. The steam drum was shortened and placed behind the boiler barrel, giving a much more conventional silhouette. Around a thousand of these were used in.: a further variant of the.; early where the tubes were grouped into bundles (of 19, for ) that shared a common header, so as to improve shared access for tube cleaning.: a form of where the furnace was opened up into a 'whistle mouth', enlarging the grate area.

The term is also applied to vertical boilers with other arrangements of tubes, such as those with.
With ( boiler behind) F Definitions Points of Interest., a fire-tube boiler with multiple joined shells of small diameter. Fairfield-Johnson boiler: a later form of operating at lower pressure (450psi rather than 850psi), but still a high superheat temperature 825 °F (441 °C).: A double-ended locomotive boiler with a central firebox, used in Fairlie's patent for double-ended articulated steam locomotives.:.: A boiler with many narrow fire-tubes inside a water drum.
A development of the, where the many smaller tubes give a much larger heating surface area for the overall boiler volume.: an attempt to squeeze the largest possible locomotive boiler into the by splitting the boiler into two drums: a fire-tube boiler beneath and a steam drum above.: A boiler with only one or two large diameter fire-tubes inside a water drum. These later developed into the.: boilers where circulation is forced by a pump, rather than relying on effect.
These may use either forced-water-circulation (e.g. ) or forced-steam-circulation (e.g. (External Superheat, D type). G Definitions Points of Interest.: a fitted with. Originally these fused the Lancashire boiler's original two flues into a single flue, with the tubes mounted in the joined section.
Later boilers kept the cylindrical flues separate and placed the tubes within them.: an early, where the outer firebox was particularly large and served as the, often highly decorated with polished brass. These were popular for early railway locomotives, from 1830 to 1850. This is another form of boiler frequently described as a '.: similar to the commonly known locomotive boiler, from. A horizontal boiler drum contains multiple fire-tubes and a separate furnace.
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. I Definitions Points of Interest.: a water-tube boiler.: a modified form of the, with an additional combustion chamber. J Definitions Points of Interest. Johnson boiler: one of the first 'modern' classes of high-pressure marine oil-fired water-tube boilers. They have a single steam drum above a single water drum. Their small-diameter water-tubes curve outwards on each side to form a cylindrical furnace.

As there is no grate or ashpan beneath, firing must be by oil. Return circulation is by external downcomers. Early versions also used at each end of the furnace, later ones had plain firebrick walls. K Definitions Points of Interest.: (sometimes Keeve or Kieve) an un-fired boiler, a pressure vessel heated by an external steam supply, used for bleaching in dyeworks and processing. In use they were continuously rotated by an engine, steam being supplied through a rotating joint in the axle. They were usually spherical, sometimes cylindrical, and some were recycled from old boiler shells. Kingdom boiler: an uncommon pattern of water-tube boiler.: Maker of fire tube boilers L Definitions Points of Interest.: a.
They are often used as marine. It was also used, unsuccessfully, for an experimental steam locomotive in East Germany in the 1950s.: a development of the, with two flues.: early with large diameter water-tubes, of 3 inches and above, rather than the later designs.: a small used in launches and smaller. A horizontal cylinder in form, with a cylindrical furnace and multiple fire-tubes. They have some resemblance to a small or, but with the fire-tubes extending beyond the furnace end, rather than folded back as a.
Sometimes small of just this form are also described as 'launch-type'. A large with a, used rarely for some steam locomotives. Of German design. A similar boiler, the, was used in the USA.: the commonly known form familiar from. A horizontal boiler drum contains multiple fire-tubes and a separate firebox.
It was used unsuccessfully on a of the 1930s. O Definitions Points of Interest.: A compact boiler capable of producing superheated steam to over 1000C at one atmosphere's pressure. P Definitions Points of Interest.:.: a form of Scotch boiler, adapted for stationary use and set in a brick surround as an external flue.: a form of small with a circular firebox, to avoid the need for.

It was invented by the Russian, whilst imprisoned in a.: a vertical, typically used in. Owing to the conditions of their use, they acquired a poor reputation for safety and.: An early naval.: with a single large flue that folds back on itself. Used in early steam locomotives.: with multiple small fire-tubes that reverse the direction of gas flow within the boiler. Individual tubes are not folded: there is usually a furnace, a combustion chamber that reverses the flow, then the tubes return from that. The is a well-known example of this type.

Robertson boiler S Definitions Points of Interest.: a high-pressure locomotive boiler, as used for the experimental. To avoid the usual problems of scale formation in a highly stressed firebox, the Schmidt system uses a separate primary circuit filled with.:.:.:.: with small-diameter tubes, 2 inch or less, rather than the older designs, with tubes of 3 inch and above. Also termed or Speedy boilers.
Smithies boiler: A development of the with added watertubes, used for model steam locomotives. The boiler was invented by F. Smithies in 1900 and developed. It consists of a cylindrical water drum hidden inside a larger drum that forms the visible part of the model. Long slightly-sloping water-tubes are mounted beneath this water drum. The advantage of the boiler over similar model boilers is the use of almost the entire water drum surface for heating, although this also tends to scorch any paintwork on the outer drum, unless this is insulated. In a later development by Greenly, the backhead of the boiler becomes a double-walled water space and straight water-tubes are led into this at an angle.: a, notable for its use of 'Swirlyflo'.
Spanner boilers were also known for their use as.:.: an extremely compact, used in the.: modern boilers, with very small volume in relation to their heating area. Boiling is thus almost instantaneous and the volume of heated, but unboiled, water is minimal.: an early, used in large stationary installations.: a formed of a single helical water-tube.: a vertical water-tube boiler for the Straker steam wagon.: a, with the boiler shell extended upwards in an annular ring, so as to always maintain the whole length of the tubes. Used in and similar, where the may be disturbed as the vehicle climbs a hill.: a 'once-through'.
