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 ...
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 ]
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.
Supercritical steam generator or Benson boiler, a high-pressure steam generator that operates in the supercritical pressure regime, such that no boiling takes place within it. 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.
A boiler is a closed vessel in which fluid (generally water) is heated.The fluid does not necessarily boil.The heated or vaporized fluid exits the boiler for use in various processes or heating applications, [1] [page needed] [2] [page needed] including water heating, central heating, boiler-based power generation, cooking, and sanitation.
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.

The inverted U-tube bundle of a Combustion Engineering steam generator. A steam generator (aka nuclear steam raising plant ('NSRP')) is a heat exchanger used to convert water into steam from heat produced in a nuclear reactor core. It is used in pressurized water reactors (PWRs), between the primary and secondary coolant loops.
