  2. Steam generator (auxiliary boiler) - Wikipedia

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

    A steam generator on a ship is an auxiliary boiler which draws high-pressure superheated steam from the vessel's propulsion system [1] to generate low pressure saturated steam. This secondary steam is then used to power auxiliary shipboard engines driving winches or pumps, or to meet any steam requirement that does not require superheating ...

  3. Marine steam engine - Wikipedia

    en.wikipedia.org/wiki/Marine_steam_engine

    A marine steam engine is a steam engine that is used to power a ship or boat. This article deals mainly with marine steam engines of the reciprocating type, which were in use from the inception of the steamboat in the early 19th century to their last years of large-scale manufacture during World War II .

  4. Marine propulsion - Wikipedia

    en.wikipedia.org/wiki/Marine_propulsion

    The last major passenger ship built with steam turbines was Fairsky, launched in 1984. Similarly, many steam ships were re-engined to improve fuel efficiency . One high-profile example was the 1968 built Queen Elizabeth 2 which had her steam turbines replaced with a diesel-electric propulsion plant in 1986.

    Monotube steam generator: A single tube, usually in a multi-layer spiral, that forms a once-through steam generator. The first of these was the Herreshoff steam generator of 1873. [38] Multi-tube boiler: fire-tube boiler with multiple small fire-tubes, rather than a single large flue.

  6. Boiler (power generation) - Wikipedia

    en.wikipedia.org/wiki/Boiler_(power_generation)

    Supercritical steam generators are frequently used for the production of electric power. They operate at supercritical pressure. In contrast to a "subcritical boiler", a supercritical steam generator operates at such a high pressure (over 3,200 psi or 22.06 MPa) that actual boiling ceases to occur, the boiler has no liquid water - steam separation.

  7. Steam generator - Wikipedia

    en.wikipedia.org/wiki/Steam_generator

    Steam generator (auxiliary boiler), a steam-powered boiler used on ships to produce a low-pressure steam, heated by a high-pressure steam supply rather than a flame. Steam generator (boiler), an oil- or gas-fired boiler, based on a low-water content monotube coil. Steam generator (nuclear power), a heat exchanger in a pressurized water nuclear ...

  9. A2W reactor - Wikipedia

    en.wikipedia.org/wiki/A2W_reactor

    Thereafter, steam flow (from the steam generators) regulates reactor power as explained below. The control rods are "shimmed" in or out to regulate average coolant temperature or lowered to the bottom of the reactor vessel to shut the reactor down — either done in a slow controlled manner or dropped rapidly during what is called a SCRAM to ...
