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

6. BASIC PRINCIPLE OF
THERMAL POWER STATION

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

8. 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

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

10.  The products of
combustion pass
through the tubes
which are surrounded
with water.
 Simple, compact and
rugged in construction.
 In this boiler water flows
inside the tubes and hot
gases flow outside the
tubes
 Further classified as
vertical ,horizontal and
inclined.
 Low initial cost
 economical only for
low pressure
 Lesser weight
 Uniform heating of all
parts
 Increased efficiency
 Better control of
temperature.

11. Removes furnaces bottom and fly ash
Small stations Large stations
use conveyer
arrangement
to carry ash
to dump sites
A sluicing system is
generally used for
removal of furnace
bottom ash.
A pneumatic system
is usually employed
for disposal of fly
ash.

12. 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.

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

h.p.or even more.
 Steam when issuing from
a small opening attains a
high velocity.
 steam is expanded in turbine
nozzle and attains a high
velocity.
standard speeds are 3000 rpm and 1500 rpm for
coupling to 500hz generators.
 Complete expansion of heat
takes place in the nozzle.
 This velocity during
 Steam pressure during the flow
expansion depends on the
initial and final heat
content of the steam
of steam remains constant.
 Thus, pressure on the two
sides of blade is the same.
 Only partial expansion of
steam takes place in the nozzle
and further expansion takes
place as the steam flows over
the rotor blades.
 There is difference in
pressure on the two sides of
the moving blade

14. 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.

15. 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 .

16. 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.

This picture shows how electricity gets to your home.

19.  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.
