  2. Boiler feedwater - Wikipedia

    en.wikipedia.org/wiki/Boiler_feedwater

    Both effects will reduce the pipe's overall thermal efficiency when used as a heat exchanger. Boiler feedwater is the water which is supplied to a boiler. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used, it is then dumped to the main ...

  3. Feedwater heater - Wikipedia

    en.wikipedia.org/wiki/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] This reduces plant operating costs and also helps to avoid thermal shock ...

  4. 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.

  5. Boiler feedwater pump - Wikipedia

    en.wikipedia.org/wiki/Boiler_feedwater_pump

    Boiler feedwater pump. A boiler feedwater pump is a specific type of pump used to pump feedwater into a steam boiler. The water may be freshly supplied or returning condensate produced as a result of the condensation of the steam produced by the boiler. These pumps are normally high pressure units that take suction from a condensate return ...

  6. Economizer - Wikipedia

    en.wikipedia.org/wiki/Economizer

    Economizer. Economizers (US and Oxford spelling), or economisers (UK), are mechanical devices intended to reduce energy consumption, or to perform useful function such as preheating a fluid. The term economizer is used for other purposes as well. Boiler, power plant, heating, refrigeration, ventilating, and air conditioning (HVAC) may all use ...

  7. Boiler (power generation) - Wikipedia

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

    Boiler (power generation) An industrial boiler, originally used for supplying steam to a stationary steam engine. 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 ...

  8. Thermal power station - Wikipedia

    en.wikipedia.org/wiki/Thermal_power_station

    A thermal power station, also known as a thermal power plant, is a type of power station in which the heat energy generated from various fuel sources (e.g., coal, natural gas, nuclear fuel, etc.) is converted to electrical energy. [1] The heat from the source is converted into mechanical energy using a thermodynamic power cycle (such as a ...

  9. Cogeneration - Wikipedia

    en.wikipedia.org/wiki/Cogeneration

    Cogeneration or combined heat and power (CHP) is the use of a heat engine [1] or power station to generate electricity and useful heat at the same time. Cogeneration is a more efficient use of fuel or heat, because otherwise- wasted heat from electricity generation is put to some productive use. Combined heat and power (CHP) plants recover ...
