  2. Scotch marine boiler - Wikipedia

    en.wikipedia.org/wiki/Scotch_marine_boiler

    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 ...

  3. O-type boiler - Wikipedia

    en.wikipedia.org/wiki/O-type_boiler

    O-type boilers first appeared as marine boilers, such as the Johnson boiler, once the switch from coal firing to oil firing began. [1] The large radiant heating area available allows a combustion rate, for a given furnace volume, of around twice that for a contemporary boiler, such as the Yarrow.

  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]

  5. Water-tube boiler - Wikipedia

    en.wikipedia.org/wiki/Water-tube_boiler

    The 'D-type' is the most common type of small- to medium-sized boilers, similar to the one shown in the schematic diagram. It is used in both stationary and marine applications. It consists of a large steam drum vertically connected to a smaller water drum (a.k.a. "mud drum") via multiple steam-generating tubes.

  6. Boiler design - Wikipedia

    en.wikipedia.org/wiki/Boiler_design

    Boiler design is the process of designing boilers used for various purposes. The main function of a boiler is to heat water to generate steam. Steam produced in a boiler can be used for a variety of purposes including space heating, sterilisation, drying, humidification and power generation. The temperature or condition of steam required for ...

  7. Steam generator (auxiliary boiler) - Wikipedia

    en.wikipedia.org/wiki/Steam_generator_(auxiliary...

    A typical generator uses inlet steam supplied at 600 psi to produce around 10,000 lb/hour at around 120 psi. [2] It is constructed as a cylindrical steel pressure vessel, either horizontal or vertical, containing a series of heating coils.

  8. Fire room - Wikipedia

    en.wikipedia.org/wiki/Fire_room

    Vessels typically contained several engines for different purposes. Main, or propulsion engines are used to turn the ship's propeller and move the ship through the water. . The fire room got its name from the days when ships burned coal to heat steam to drive the steam engines or turbines; the room was where the stokers spent their days shoveling coal continuously onto the grates under the ...

  9. Boiler - Wikipedia

    en.wikipedia.org/wiki/Boiler

    Fire-tube boilers usually have a comparatively low rate of steam production, but high steam storage capacity. Fire-tube boilers mostly burn solid fuels, but are readily adaptable to those of the liquid or gas variety. Fire-tube boilers may also be referred to as "scotch-marine" or "marine" type boilers.
