2. Steam generator (nuclear power) - Wikipedia

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

   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 ...

3. Boiler (power generation) - Wikipedia

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

   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 steam generator. A boiler or steam generator is used wherever a source of steam is required.

   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.

5. 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 ...

6. Supercritical steam generator - Wikipedia

   en.wikipedia.org/wiki/Supercritical_steam_generator

   A supercritical steam generator is a type of boiler that operates at supercritical pressure and temperature, frequently used in the production of electric power. In contrast to a subcritical boiler in which steam bubbles form, a supercritical steam generator operates above the critical pressure – 22 megapascals (3,200 psi ) and temperature ...

7. Pressurizer (nuclear power) - Wikipedia

   en.wikipedia.org/wiki/Pressurizer_(nuclear_power)

   In the event that pressurizer pressure exceeds a certain maximum, there is a relief valve called the pilot-operated relief valve (PORV) on top of the pressurizer which opens to allow steam from the steam bubble to leave the pressurizer in order to reduce the pressure in the pressurizer. This steam is routed to a large tank (or tanks) in the ...
