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.
The Clayton steam generator is similar to the Stone-Vapor, but the burner and flow directions are reversed. The heating coil is mounted within a simple cylindrical casing. Rather than helical, cylindrical layers, the Clayton coils are arranged as layers of flat spirals. Water is pumped into the top layers and forced downwards.
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.
This Babcock & Wilcox nuclear steam generator moved in a special train (restricted to 20 mph) via the Penn Central Railroad and Southern Railway from Barberton, Ohio to a Duke Energy site in Oconee, S.C. This generator weights 1,140,000 lbs and is a record shipment for the Railroad at that time (1970). A once-through steam generator A VVER ...
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;
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 ...
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 ).
