POWER PLANT
A power plant is a facility for the generation of electric power. The term is also used to refer to the engine in ships, aircraft and other large vehicles.
At the center of nearly all power stations is a generator, a rotating machine that converts mechanical energy into electrical energy by creating relative motion between a magnetic field and a conductor. The energy source harnessed to turn the generator varies widely from installation to installation.
In thermal power plants mechanical power is produced by a heat engine which transforms thermal energy, often from combustion of a fuel, into rotational energy. All thermal energy cannot be transformed to mechanical power, according to the second law of thermodynamics. Therefore, thermal power plants also produce low-temperature heat. If no use is found for the heat, it has to be rejected. If reject heat is employed as useful heat, the power plant is referred to as a cogeneration power plant or CHP (combined heat-and-power) plant.
Thermal power stations are often easily identified by cooling towers, huge cylindrical chimney-like structures that release the waste heat to the atmosphere.
Other power stations use the energy of water (waves, tides, or rivers confined by hydroelectric dams), wind, or sunlight.
GENERAL LAYOUT OF THE PLANT
Though each plant is unique in itself in terms of specific features and functionalities, still there is a broad outline to which all thermal power plants confirm to and in this article we will study about the general layout of a typical power plant.
