2. 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 ...

3. Water heating - Wikipedia

   en.wikipedia.org/wiki/Water_heating

   In traditional plumbing in the UK, the space-heating boiler is set up to heat a separate hot water cylinder or water heater for potable hot water. Such water heaters are often fitted with an auxiliary electrical immersion heater for use if the boiler is out of action for a time. Heat from the space-heating boiler is transferred to the water ...

4. Thermal power station - Wikipedia

   en.wikipedia.org/wiki/Thermal_power_station

   A Rankine cycle with a two-stage steam turbine and a single feed water heater. The energy efficiency of a conventional thermal power station is defined as saleable energy produced as a percent of the heating value of the fuel consumed. A simple cycle gas turbine achieves energy conversion efficiencies from 20 to 35%. [5]

5. Boiler (power generation) - Wikipedia

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

   The steam produced has lower density than the water and therefore will accumulate at the highest level in the vessel; its temperature will remain at boiling point and will only increase as pressure increases. Steam in this state (in equilibrium with the liquid water which is being evaporated within the boiler) is named "saturated steam". For ...

6. Boiler feedwater - Wikipedia

   en.wikipedia.org/wiki/Boiler_feedwater

   The water is reused and needs to be treated to continue efficient operations. Boiler water must be treated in order to be proficient in producing steam. Boiler water is treated to prevent scaling, corrosion, foaming, and priming. Chemicals are put into boiler water through the chemical feed tank to keep the water within chemical range.
