  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. Steam generator (boiler) - Wikipedia

    en.wikipedia.org/wiki/Steam_generator_(boiler)

    A steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube , arranged as a single, or monotube , coil. Circulation is once-through and pumped under pressure, as a forced-circulation boiler . [ 1 ]

  4. 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 ...

    Secondary feedwater enters the "shell" side of the steam generator through the feedring, which is a torus with short, inverted-J shaped nozzles spaced around its major circumference. Secondary water continues down the downcomer, which is the annular space between the outer shell of the steam generator and the shroud covering the tube bundle.

  6. Boiler (power generation) - Wikipedia

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

    A boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi ) but, at pressures above this, it is more usual to speak of a ...

  7. Heat recovery steam generator - Wikipedia

    en.wikipedia.org/wiki/Heat_recovery_steam_generator

    A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycle).

  8. Monotube steam generator - Wikipedia

    en.wikipedia.org/wiki/Monotube_steam_generator

    Herreshoff steam generator in a Peruvian torpedo boat of 1879. A monotube steam generator is a type of steam generator consisting of a single tube, usually in a multi-layer spiral, that forms a once-through steam generator (OTSG). The first of these was the Herreshoff steam generator of 1873. [1]
