2. Introduction of Kota Super
Thermal Power Plant It was established in 1983.
 It is located at the left bank of the Chambal river at the
upstream of the Kota Bairage.
 1st and 2nd units are of 110 MW each.
 3rd, 4th and 5th units are of 210 MW.
 6th and 7th units are of 195 MW.
Total generation capacity :
(110+110+210+210+210+195+195)=1240 MW.
 Favorable conditions :
 Abundant quantity of clean cooling water.
 Good transport facility.
Concentration of load in Kota region due to large
number of industries.

Power Plant

7. Coal Handling Plant
•Wagon unloading system
•Crushing system
•Conveying system
Coal handling plant section

8. Wagon Unloading System
•Unload the coal from
wagon to hopper with the
help of wagon Tripler .
• Hopper allow to pass
coal pieces ≤ 200 mm.
•From hopper coal falls
on vibrator which is
supported by roller.

9. Conveying System
•Belt are used to convey
coal from coal handling
plant to furnace.
•Specification:-
 Belt width : 1400 mm
 Speed : 2.2 m/sec
 Total install power :
360 KW
 Capacity : 1350/750
ton/hr
No. of conveyor: 38

10. Crushing System
• CRUSHER HOUSE: It
consists of crushers which
are used to crush the coal
to 20 mm size.
•Two Types
Primary crusher
• Rail crusher
•Rotary crusher
Secondary crusher

11. Boiler
•It is a closed vessel in which water under pressure is converted
into steam.
•Hot water or steam used to transfer heat to a process.
•A boiler is always designed to absorb maximum amount of
heat released in process of combustion.
•Furnace: It is a primary part of boiler where the fuel is burnt to
liberate the heat energy.

12. Boiler

13. Super heater
• Super Heater consists group of tubes.
• The tubes are heated by the heat of combustion gases during
their passes from furnace to chimney, so the temperature
increased.
• Super heater remove the moisture from the steam leaving from
the boiler tubes.

14. Steam Turbine
•It is a machine in which a
shaft is rotated steadily by
reaction of steam, air upon
blades of a wheel.
•When steam is used then
it is called steam turbine.
• It works on modified
rankine cycle.

Kinetic Energy

15. Economizer
• Economizer is a device which recover heat from the flue
gases on their way to chimney.
• It increases the 10-12 % efficiency of the plant.

16. Electrical Generator
•An electrical generator is
a machine which converts
mechanical energy into
electrical energy through
electro mechanical energy
conversion.
•The generator is driven by
directly coupled steam
turbine at a speed of 3000

18. Water Treatment Plant
Pressure filter removes
undisclosed impurities from raw
water.
Carbon filter removes excess
chlorine from clarified water.
D.M. plant removes dissolved
impurities from clarified water.
Conductivity, pH & silica
content of this water must be
checked time to time.
D.M. water must be in ratio of
1:8

19. Cooling System
• In KSTPS hydrogen cooling
system is employed for generator
cooling.
• Hydrogen used because of its
superior cooling properties and
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
•It can be subdivided into 3
sub plants :
•Fuel and ash plant
•Air and Gas plant
•Ash disposal and dust
collection plant.
•In thermal plants 25% is
furnace bottom ash and 75%
is pulverized fuel ash.
•Electrostatic precipitator in
ash handling plant to remove
fly ash .
