2. Superheated steam - Wikipedia

   en.wikipedia.org/wiki/Superheated_steam

   Superheated steam is also not useful for heating; while it has more energy and can do more work than saturated steam, its heat content is much less useful. This is because superheated steam has the same heat transfer coefficient of air, making it an insulator - a poor conductor of heat. Saturated steam has a much higher wall heat transfer ...

3. Steam - Wikipedia

   en.wikipedia.org/wiki/Steam

   Steam is a capacious reservoir for thermal energy because of water's high heat of vaporization. Fireless steam locomotives were steam locomotives that operated from a supply of steam stored on board in a large tank resembling a conventional locomotive's boiler.

4. New York City steam system - Wikipedia

   en.wikipedia.org/wiki/New_York_City_steam_system

   Approximately 30% of the ConEd steam system's installed capacity and 50% of the annual steam generated comes from cogeneration. [7] Cogeneration and Heat Recovery Steam Generation (HRSG) significantly increase the fuel efficiency of cogenerated electricity and thereby reduce the emission of pollutants, such as NOx, sulfur dioxide, carbon dioxide, and particulate matter, as well as the city's ...

5. 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 ...

6. Steam–electric power station - Wikipedia

   en.wikipedia.org/wiki/Steam–electric_power_station

   The efficiency of a conventional steam–electric power plant, defined as energy produced by the plant divided by the heating value of the fuel consumed by it, is typically 33 to 48%, limited as all heat engines are by the laws of thermodynamics (See: Carnot cycle). The rest of the energy must leave the plant in the form of heat.

7. Steam turbine - Wikipedia

   en.wikipedia.org/wiki/Steam_turbine

   A steam turbine or steam turbine engine is a machine or heat engine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884.
