The document summarizes the key components and technical details of the Kota Super Thermal Power Station located in Kota, India. It has a total installed capacity of 1240 MW distributed across 7 units with capacities ranging from 110 MW to 210 MW. The main parts of the power station include the coal handling plant, boiler, superheater, steam turbine, economizer, generator, water treatment plant, ash handling plant, and control room. The coal handling plant handles the intake, crushing and conveying of coal to the furnace. The boiler converts the chemical energy of combustion into thermal energy to produce steam. The steam then powers the steam turbine which drives the electrical generator.

3. It was established in 1983.
It is located at the left bank of the CHAMBAL River at the
upstream of KOTA BAIRAJ.
1st & 2nd units are of 110 MW each.
3rd ,4th &5th units are of 210 MW .
6th & 7 unit of 195 MW.
Total generation capacity
(110+110+210+210+210+195+195) =1240 MW
Favorable condition
Abundant quantity of clean cooling water.
Good transport facility

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

9. Wagon unloading system
 Unload the coal from
wagon to hopper with
the help of wagon
Tripler.
 Hopper allows to pass
coal pieces ≤ 200mm
 From hopper coal fall
on vibrator which is
supported by roller.

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

11. Crushing system
 CRUSHER HOUSE:- It
consists of crushers which
are used to crush the coal
to 20 mm size.
 Two types
 Primary crusher
o Rail crusher
o Rotary breaker
 Secondary crusher

12. 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 primary part of boiler where the fuel is
burnt to liberate the heat energy.

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

15. 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.

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

17. •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 r.p.m.

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 the
ratio of 1:8

19. Ash Handling Plant
 In thermal plants 25%
is furnace bottom ash
and 75% is pulverized
fuel ash.
 Electrostatic
Precipitator is used in
ash handling plant to
remove fly ash.
