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 ...
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.
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 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 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.
Steam generator emergency cooling down system; Emergency power supply system (diesel-generator set). The profile of the passive safety systems is as follows: Passive part of the core emergency cooling system; Passive core-flooding system; Water supply system from the fuel pond to primary circuit; Stem of passive heat removal from steam generator;
