In all power generating stations except solar power generating station employee alternator to generate electrical energy. An alternator is a rotating machine which can produce electricity only when it rotates. Hence there must be a prime mover which helps to turn the alternator. The primary arrangement of all power plants is to rotate the prime mover so that alternator can generate required electricity. In gas turbine power plant we use high pressure and temperature air instead of high pressure

The main components of a gas turbine power plant are the compressor, regenerator, combustion chamber, gas turbine, alternator, and starting motor.CompressorAir compressor used in a gas turbine power plant is mainly of the rotary type. The air filter is attached at the inlet of the compressor where air gets filtered from dust. The rotary blades attached to the shaft push the air between stationary blocks, and consequently, the pressure of the air is increased. High pressure air is available at th

A diesel power plant is a type of power plant that uses a diesel engine as the prime mover to drive an alternator and generate electricity. Diesel power plants are mainly used for small-scale power generation or as backup sources of electricity in remote areas or during emergencies. In this article, we will discuss the components, working principles, advantages, disadvantages, and applications of diesel power plants.What is a Diesel Power Plant?A diesel power plant is defined as a power plant th

We can generate electrical power by means of nuclear power. In nuclear power station, generates electrical power by nuclear reaction. Here, heavy radioactive elements such as Uranium (U235) or Thorium (Th232) are subjected to nuclear fission. This fission is done in a special apparatus called reactor.What is nuclear fission?In the fission process, the nuclei of heavy radioactive atoms are broken into two nearly equal parts. During this breaking of nuclei, a huge quantity of energy is released. T

In hydroelectric power station the kinetic energy developed due to gravity in a falling water from higher to lower head is utilised to rotate a turbine to produce electricity. The potential energy stored in the water at upper water level will release as kinetic energy when it falls to the lower water level. This turbine rotates when the following water strikes the turbine blades. To achieve a head difference of water hydroelectric electric power station are generally constructed in hilly areas.

Thesteam turbineis a favourite prime mover in a steam power generating plants. The steam turbine may be of capacity from 5 megawatts 2000 megawatt.The advantages of a steam turbine over a diesel engine are as follows. The size of a steam turbine is much smaller than that of an equivalent diesel engine. The size of a 30-megawatt steam turbine is same as a 5-megawatt diesel engine. Construction wise the steam turbine is much simpler than a diesel engine. The rotor shaft, blades, steam control valv

Water hammer or hydraulic shock phenomenon and can be understood as abrupt collision of fast moving solid slug with in the piping system with any obstruction that may be bend, valve etc. Thus a water hammer is defined as a sudden increase in pressure on account of hindrance to fluid motion or direction-change.Example It happens during the charging or warming-up of the longer steam line during the initial start-up operation and also because of steam and condensate mixing. Water hammer is somethin

The considerable increase of the demand of electricity throughout the world has resulted in increased size of power plant. The process of electrical power generation, in a coal fired thermal power plant is one of the most widespread and conventional methods, of bulk power generation all over, as it vastly feeds the power requirement of a 7 billon plus population all across the globe.The increased size needs increase in fuel requirement. But as we all must be knowing, the availability of coal ben

A thermal power generating plant works based on the Rankine Cycle. There are mainly three primary inputs given to thermal power generating plants for producing electricity. These three most essential elements are coal, air, and water.Coal is used as fuel here because we are going to draw the flow diagram of a coal thermal power generating plant. Coal creates required heat energy by combustion in the furnace.Air is supplied to the furnace to accelerate the combustion rate of the coal and to conti

What is a Thermal Power Plant?A thermal power generation plant or thermal power station is the most conventional source of electric power. The thermal power plant is also referred to as a coal thermal power plant and steam turbine power plant.Let’s dive into how a thermal power plan works.Theory of Thermal Power StationThe theory of thermal power stations or the working of the thermal power stations is very simple. A power generation plant mainly consists of alternator runs with help of a steam
