GENERATION OF ELECTRICITY
Prime mover coupled to Alternator.
Prime mover is driven by energy obtained from various sources such as
burning of fuel , pressure of water, force of wind etc.

THERMAL POWER PLANT• A generating station which converts heat energy of coal combustion
into electrical energy is known as a steam power station.• Steam is produced in the boiler by utilizing the heat of coal
combustion. The steam is then expanded in the steam turbine and is condensed in a condenser to be fed into the boiler again. The steam turbine drives the alternator which converts mechanical energy of the turbine into electrical energy.

THE MOST IMPORTANT CONSTITUENTS OF A THERMAL POWER STATION ARE:
a. Steam generating equipmentb. Condenserc. Prime moverd. Electrical equipment
Steam generating equipment includes:
• Boiler• Superheater• Economiser• Air Pre-heater

BoilerA boiler is closed vessel in which water is converted into steam by utilising the heat of coal combustion. Steam boilers are broadly classified into following two types:(a) Water tube boilers (b) Fire tube boilers
In a water tube boiler, water flows through the tubes and the hot gases of combustion flow over these tubes. Water-tube boilers are used for high-pressure boilers

A FIRE TUBE BOILER, is just opposite of water tube boiler in structure. The hot products of combustion gases pass through the tubes surrounded by water.

SUPER HEATER A device which removes last traces of moisture. It helps in reduction in requirement of steam
quantity. steam being dry reduces the mechanical resistance
of turbine. No corrosion at the turbine blades.
![Page 11: PRESENTATION OF INDUSTRIAL TRAINING ON THERMAL POWER PLANT AT NTPC, SHAKTINAGAR](https://reader036.fdocuments.us/reader036/viewer/2022081800/56816439550346895dd60176/html5/thumbnails/11.jpg)
ECONOMISER AND AIR PRE-HEATER
They are such devices which recover the heat from the flue gases on their way to chimney and raise the temperature of feed water.
Air Pre-heaters recover the heat from the flue gases leaving the economiser and heat the incoming air required for combustion
![Page 12: PRESENTATION OF INDUSTRIAL TRAINING ON THERMAL POWER PLANT AT NTPC, SHAKTINAGAR](https://reader036.fdocuments.us/reader036/viewer/2022081800/56816439550346895dd60176/html5/thumbnails/12.jpg)
CONDENSER Which condenses the steam at the exhaust of
turbine. It creates a very low pressure at the exhaust of
turbine, this helps in converting heat energy of steam into mechanical energy in the prime mover.
The condensed steam can be used as feed water to the boiler.

PRIME MOVER (I.E. TURBINE)A steam turbine is a mechanical device that extracts thermal energy from pressurized steam, and converts it into mechanical energy.About 86% of all electric generation in the world is by use of steam turbines.It has almost completely replaced the reciprocating piston steam engine.

ELECTRICAL EQUIPMENTSTurbo generator An turbo generator is coupled to a steam turbine and converts mechanical energy of the turbine into electrical energy.It may be hydrogen or air cooled. Rating of turbo generator is normally 200MW & 500MW. Transformers(a) main step-transformers, which steps-up generated voltage transmission of power(b) station transformers, general purpose(c) auxiliary transformers, which supply to individual unit-auxiliaries. Switchgearwhich locates fault on the system and isolate faulty part from healthy section.It contains circuit breakers, relays, switches and other control devices.

CHP follows three coal paths:1.Path A-from track hopper to bunkers2.Path B-from track hopper to stockyard.3.Path C-from stockyard to bunker.

Generally thermal power stations use coal mills or called coal firing system.
Coal is reduced to fineness (-20mm). This fine powdered coal is called pulverized coal and is
carried forward to the burner by air through pipes.

ASH HANDLING TECHNIQUE A natural result from the burning of fossil fuels, particularly coal, is
the emission of flyash. Ash is mineral matter present in the fuel. For a pulverized coal unit, 60-80% of ash leaves with the flue gas.
Electrostatic precipitator has series of collecting & emitting electrodes in a chamber.
At the inlet of the chamber there are distributer screen. Hooper and flushing system form a base of chamber. Efficiency of ESP is approx. 99.8%

SWITCHYARDSwitchyard is considered as the HEART of power
plant.It is a junction , which carries the generated power
to its destination.It is basically an open area where many different
kind of outdoor equipments are located. eg: busbars , transformers , circuit breakers etc.
Switch yards can be of 400KV, 132KV.
