3. Rajasthan's first major Coal fired Power
plant established in the year 1983.
Located on the left bank of the Chambal
River near Kota.
Total installed capacity of KSTPS is
1240MW.

4. Electricity by definition is electric current
or voltage that is used as a power source.
This electric power is generated in a power
plant,and then sent out over a power grid to your
homes, and ultimately to our power outlets.

6. A generating station which converts heat
energy of coal combustion into electrical
energy is known as Thermal Power
Station.

8. BASIC PRINCIPLE OF
THERMAL POWER STATION

9.  Coal handling plant
 Pulverizing plant
 Boiler
 Air pre heater
 Ash handling plant
 Super heater
 Turbine
 Economiser
 Condenser
 Dearator
 Alternator

10. The pulverized
coal
is fed to the
boiler
by conveyor belts
From the coal storage
plant, coal is delivered
to the coal
handling
plant where it is
pulverized

11. coal is pulverized i.e. ground to dust like size and
carried to the furnace in a stream of hot air
 Rate of combustion can be
controlled.
 Even low grade coal can be
used.
 The percentage of excess air
required is low.
 Investment cost of plant is
increased.
 Explosion hazards exist.
 Auxiliary power consumption
of the plant increased.

14. A super heater is a device which superheats the
steam, it raises the temperature of steam above
boiling point of water.
Increases the overall efficiency of the steam.
A super heater consists of a group of tubes made
of special alloy such as chromium-molybdenum.
These tubes are heated by the heat of the flue
gases.

15. A steam turbine converts heat energy of a steam
into mechanical energy and drives the generator.

16. Economiser
The purpose of economizer is to heat feed water so as to
recover apart of heat, which would otherwise be lost through
flue gases.
Flue gas out of the boilers carry a lot of heat. An economizer
extracts a part of this heat from the flue gases and uses it for
heating feed water.

17. Condensate the exhaust steam from the low
pressure turbine.
The surface condenser is a shell and tube heat
exchanger in which cooling water is circulated
through the tubes.
The steam enters the shell where it is cooled and
converted to condensate (water) by flowing over the
tubes .

18. Generator is the main part of thermal power station.
A generator is a machine which converts
mechanical energy into electrical energy.
Alternator is Mechanically Coupled with the Steam
Turbine.

20. Conclusion
 We have learn’t how electricity is produced in thermal power
plant and its main and auxiliary equipments.
 We have seen that the fuel sources that provide energy are not
going to be last forever.
 We need to realize that and make worldwide leaders aware of the
energy crisis. If this continuous, we won’t have any energy left for
coming generation.
 So, start saving electricity and make the environment green and
pollution free.
