Steam power plant
  • The steam power plant is an arrangment that
    converts the energy of fuel into mechanical
  • BASIC CYCLE Heat generated in the furnace is
    transmitted to the boiler where water is changed

Steam power plant
  • BASIC CYCLE To convert the heat energy of steam
    into mechanical work, the steam is admitted to
    the turbine through the nozzles, where the energy
    is transformed into kinetic energy. The steam
    expands and while it leaves the nozzle its energy
    is converted into useful work at the turbine
  • In passing through the turbines, the steam is
    reduced in pressure and temperature. The exhaust
    steam is then condensed into water and returned
    to the boiler for the repetition of the cycle.

Elements of the steam power plant
  • THE MAIN ELEMENTS include the furnace, boiler,
    engine and condenser.
  • THE AUXILIARIES include the feed pumps, feed
    heaters, air heaters, superheaters, condensate
    pumps, air ejector, de-aerator...

Units of energy
  • The mechanical energy is expressed in horse power
    (h.p.) or according to the SI system in kilowatts
    (kW). 1 British horse power0.7457kW
  • To measure the heat energy of steam, the British
    thermal unit (B.t.u.) is used. According to the
    SI system, the unit of thermal energy is joule.
  • 1 B.t.u. kJ (kilojoule)

  • What is the purpose of a steam power plant?
  • What is steam? What does it act as?
  • What is the job of the engine?
  • What is a boiler? What may it consist of?
  • By what units do we measure heat energy and
    mechanical energy?
  • Where does the conversion of heat energy into
    mechanical energy take place?
  • What happens to steam after having performed
  • Describe the basic cycle of the steam power

Various steam power plants
  • In fossil-fueled power plants, steam generator
    refers to a furnace that burns the fossil fuel to
    boil water to generate steam.
  • In the nuclear plant, steam generator refers to a
    specific type of large heat exchanger used in a
    pressurized water reactor (PWR) to thermally
    connect the primary (reactor plant) and secondary
    (steam plant) systems, which generates steam. In
    a nuclear reactor, water is boiled to generate
    steam directly in the reactor itself and there
    are no units called steam generators.
  • In some industrial settings, there can also be
    steam-producing heat exchangers called heat
    recovery steam generators (HRSG) which utilize
    heat from some industrial process.
