2. 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.

3. Feedwater heater - Wikipedia

   en.wikipedia.org/wiki/Feedwater_heater

   A Rankine cycle with two steam turbines and a single open feedwater heater. A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. [1] [2] [3] Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system ...

4. Electric steam boiler - Wikipedia

   en.wikipedia.org/wiki/Electric_steam_boiler

   Water from the system or holding tank is then run over or near this hot element in a pipe or tank, heating the water to a suitable temperature, then making the water hot enough to boil and become saturated steam, [1] at which point the saturated steam is transported to wherever it is needed via the steam pipes that exit the body of the electric ...

5. Combined cycle power plant - Wikipedia

   en.wikipedia.org/wiki/Combined_cycle_power_plant

   Transfer of heat energy from high temperature exhaust gas to water and steam takes place in a waste heat recovery boiler in the bottoming cycle. During the constant pressure process 4-1 the exhaust gases from the gas turbine reject heat. The feed water, wet and super heated steam absorb some of this heat in the process a-b, b-c and c-d.

6. Heat recovery steam generator - Wikipedia

   en.wikipedia.org/wiki/Heat_recovery_steam_generator

   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 ).

7. Steam–electric power station - Wikipedia

   en.wikipedia.org/wiki/Steam–electric_power_station

   The condensate pump then pumps the condensate water through a feedwater heater, which raises the temperature of the water by using extraction steam from various stages of the turbine. [5] [6] Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system. [9]
