2. Energy conversion efficiency - Wikipedia

   en.wikipedia.org/wiki/Energy_conversion_efficiency

   For example, an ideal fuel cell operating at a temperature of 25 °C having gaseous hydrogen and gaseous oxygen as inputs and liquid water as the output could produce a theoretical maximum amount of electrical energy of 237.129 kJ (0.06587 kWh) per gram mol (18.0154 gram) of water produced and would require 48.701 kJ (0.01353 kWh) per gram mol ...

   en.wikipedia.org/wiki/Electric_steam_boiler

   Electric steam boiler on the training ship Golden Bear. An electric steam boiler is a type of boiler where the steam is generated using electricity, rather than through the combustion of a fuel source. Such boilers are used to generate steam for process purposes in many locations, for example laundries, food processing factories and hospitals ...

4. Boiler (power generation) - Wikipedia

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

   L.D. Porta gives the following equation determining the efficiency of a steam locomotive, applicable to steam engines of all kinds: power (kW) = steam Production (kg h −1)/Specific steam consumption (kg/kW h). A greater quantity of steam can be generated from a given quantity of water by superheating it.

9. Steam–electric power station - Wikipedia

   en.wikipedia.org/wiki/Steam–electric_power_station

   In the case of a conventional steam–electric power plant using a drum boiler, the surface condenser removes the latent heat of vaporization from the steam as it changes states from vapor to liquid. The condensate pump then pumps the condensate water through a feedwater heater , which raises the temperature of the water by using extraction ...
