Thermal power plants convert the heat from combustion of fuels like coal into electrical energy. The Tuticorin Thermal Power Station is located along the Bay of Bengal in Tamil Nadu, India, consists of 5 units that generate a total of 1050MW of power. Coal is delivered by train and ship, ground into powder at mills, and burned in boilers to heat water into steam. The high-pressure steam spins turbines connected to generators that produce electricity.

1. TUTICORIN THERMAL POWER STATION

2. INTRODUCTION
• In January 1882 the world’s first public coal-fired power station started.
• It was names as Edison Electric Light Station, was built in London.
• A project of Thomas Edison organized by Edward Johnson.
• In thermal generating stations coal, oil, natural gas etc. There employed as
primary sources of energy.

3. DEFINITION & CONSTRUCTION
• A Thermal Power Plant converts the heat energy of coal into electrical enthey.
• It is constructed in approx 400 Acre.
• Located in Sea side above the Bay of Bengal
• There are 5units. 210Mw for each Unit Total 1050Mw
Unit 1: July 9, 1979 Unit 2: December 17,
1980
Unit 3: April 16, 1982 Unit 4: February 11,
1992
Unit 5: March 31, 1991

4. WORKING PRINCIPLE
• First the water is taken into the boiler from a water source. The boiler is heated
with the help of coal.
• The increase in temperature helps in the transformation of water into steam. The
steam generated in the boiler is sent through a steam turbine.
• A generator is connected to the steam turbine.
• The turbine has blades that rotate with high velocity. When steam flows across
them. This rotation of turbine blades is used to generate electricity.

5. MAIN EQUIPMENT
• Coal Plant • Turbine
• Mills • Economizer
• CST Tank • Air preheater
• Feed Water Tank • Generator
• Boiler • Chimney

6. COAL PLANT
• For TTPS coal is Supplied by Coal India Pvt Ltd.
• Coal is Comes to TTPS through the Train and Ship’s.
• Then it Carry on by Conveyors to Mills.

7. MILLS
• In mills there are 6 mills.
• 5 mills are in service and one is Stand by
• In a mill consist of 3 Rollers.
• Coal is Get into bowl and roller rotates
and it become Powder form.

8. CST TANK
• Good water is taken from thamirabarani river.
• Water get Demineralized in TTPS.
• Remove all minerals and salts from the water
• DM water is Stored in CST Tank.

9. FEED WATER TANK
• From the CST Tank, DM water is feed to Feed Water Tank.
• Now the DM water consist of some gases.
• Gages such as oxygen and carbon dioxide.
• It removes all these gases in DM water.
• Then it supplied to the boiler.

10. BOILER
• The function of boiler is to generate steam.
• At desired pressure and temperature by transferring heat.
• It is produced by burning of fuel in a furnace to change water into steam.
• Boiler is maintained at 540°C

11. TURBINE
• In thermal power plants generally 3 turbines are used to increases the efficiency.
1.High pressure turbine
2.Intermediate pressure turbine
3.Low pressure turbine

12. ECONOMIZER
• Economizers are heat exchangers that transfer the heat in the flue gas to another
medium.
• Flue gases coming out of the boiler carry lot of heat. An economizer extracts a
part of this heat from flue gases and uses it for heating feed water.
• Saving coal consumption and higher boiler efficiency.

13. AIR PREHEATER
• It is placed between the economizer and the chimney.
• A device, which increases the tempurature of air before it supply to the furnance
using heat from flue gases passing through chimney.

14. GENERATOR
• In a turbine generator, a moving by steam
• A series of blades mounted on a rotor shaft.
• It converts the mechanical (kinetic) energy of the rotor to electrical energy.

15. GENERATOR

16. ELECTROSTATIC PRECIPITATOR
• Electrostatic precipitators collect dust in the flue gas produced by boiler.
• It removes Ash from a gas stream by using electrical energy to charge particles
either positively or negatively.
• The charged particles are then attracted to collector plates carrying the opposite
charge.
• Then collected ash are stored in ash handling plant.

17. ELECTROSTATIC PRECIPITATOR

18. CHIMNEY
• The function of chimney to carry out smoke from the boiler.
• The height of the chimney is 120mts.
• To discharge the flue gases high in the atmosphere to maintain the cleanliness of
the surrounding atmospheric air.

19. ADVANTAGES
• The initial investment cost is also less as compared to the other types of power
plants.
• The installation and construction of the thermal power plant causes no major
environmental damage.
• Some kind of Fishes Growth are so well in Thermal Power Station surrounding .
Used to export to many Countries

20. DISADVANTAGES
• It pollutes the atmosphere due to producing large amount of smoke.
• Higher maintenance cost and operational cost.
• Huge requirement of water.
