The document provides information about the Kota Super Thermal Power Station (KSTPS) in Kota, Rajasthan. It discusses the key stages and features of the power station, including that it began operations in 1983, has a total generation capacity of 1240 MW from 7 units, and sources coal from local mines to power its boilers. The power station uses a steam turbine generator process to convert the thermal energy of steam into electrical energy.

4. SALIENT FEATURES
LOCATION
Ideally on the left bank of Chambal River at Up Stream of
Kota Barrage.
COAL
Coal India limited supply coal from its coal producing
subsidiaries BCCL, SECL & ECL through railway wagons
WATER
The source of water for power station is reservoir formed
by Kota Barrage on the Chambal River
LAND
Land measuring approx. 250 hectares was required for
the project in 1976

5. GENERAL LAYOUT AND BASIC IDEA:
 The conversion from coal to electricity takes place in three
stages.
 Stage 1
 The first conversion of energy takes place in the boiler.
Coal is burnt in the boiler furnace to produce heat.
Carbon in the coal and Oxygen in the air combine to
produce Carbon Dioxide and heat.
 Stage 2
 The second stage is the thermodynamic process.
 The heat from combustion of the coal boils water in the
boiler to produce steam. In modern power plant, boilers
produce steam at a high pressure and temperature.
 The steam is then piped to a turbine.
 The high pressure steam impinges and expands across a
number of sets of blades in the turbine.

6.  The impulse and the thrust created rotates the turbine.
 The steam is then condensed and pumped back into the
boiler to repeat the cycle.
 Stage 3
 In the third stage, rotation of the turbine rotates
the generator rotor to produce electricity based of Faraday’s
Principle of electromagnetic induction.
 Control system of station is based on Rankin Cycle.
 To increase the heat economy and efficiency we use
number of modification in the plant.

8. COAL HANDLING PLANT

9. SALIENT FEATURES
The coal is brought to the KSTPS
from BHARAT COKING COAL
LTD.
There are 14 tracks for
transportation.
Everyday 3- 4 trains of coal are
unloaded, each train consists 58
wagons.
Coal is unloaded from wagons by
means of WAGON TRIPPLER.
a. Wagons are rotated upside down
through an angle 180 degree.
b. The unloaded coal is transported to
crusher house with the help of
conveyer belts.

10. Boiler is a closed vessel in
which water, under
pressure, is converted into
steam by absorbing heat
released in process of
combustion.
In KSTPS boiler used is
water tube; pulverised fuel
fired; single drum type;
tangential firing system.

11. Technical Specifications
 1).Type Water Tube Boiler
 2).Make BHEL
 3).Capacity 375 tonnes per hour
 4).Steam pressure 139 kg/ sq. cm
 5).Efficiency 86.6%
 6).Steam temperature 540 deg.

12. Air pre heater
Heat energy contained by flue gases is utilized to increase
the temperature of air entering the boiler.
Reheater
Heats up steam going from high pressure turbine to
intermediate pressure turbine.
Super heater
Removes moisture present in steam going to turbine.
Economiser
Flue gases leaving boiler is passed through economiser to
increase temperature of water entering boiler drum.

13. STEAM TURBINE

14. INTRODUCTION
 Steam Turbine is a machine in which a shaft is
rotated steadily by impact or reaction steam
upon blades of a wheel.
 It converts the potential or kinetic energy of
the working substance into mechanical power
by virtue of dynamic action of working
substance.

15. PRINCIPLE OF OPERATION
 Working of the steam turbine depends upon
the dynamic action of Steam.
 The steam is caused to fall in pressure in a
passage of nozzle: due to this fall in pressure
a certain amount of heat energy is converted
into mechanical kinetic energy and the
steam is set moving with a greater velocity.

17. Designed for continuous operation at the rated
output.
Directly coupled with steam turbine, rotated at
high speed of 3000 RPM.
Two major parts:-
(i) Stator
(ii) Rotor
Major parts of stator are
(i) Stator frame.
(ii)Stator core.
(iii)Stator bars.
(iv)Stator windings.

18. Condenses steam coming out from turbine back into
water

19. Cooling System
 In KSTPS hydrogen cooling system
is employed for generator cooling.
 Hydrogen is used because of its
superior cooling properties & low
density.
 Thermal conductivity of H2 7.3
times of air.
 Seal oil system are used in
turbine for less friction in
bearing.
 Water cooling also used for any
kind of fire.

20. ASH HANDLING PLANT
This plant can be divided into three sub plants as follows :-
1)Fuel and Ash Plant:-
It is specially designed for bottom ash and fly ash in electro
static precipitator economizer and air pre-
heaters hoppers.
2)Air and Gas Plant:-
The flue gases after passing through the Electro-
Static Precipitator is exhausted through chimney.
3) Ash Disposal and & Dust Collection Plant:-
Dry free fly ash is collected in two number of 31 fly ash hopper
which are handled by two independent fly ash system.
