Kota Super Thermal Power Station (KSTPS) is a coal-based power plant located in Rajasthan, India. It has a total installed capacity of 1240 MW generated across 7 units. The plant receives coal via train from nearby mines and uses water from the Chambal River. It employs a Rankine cycle with a coal handling plant, ash handling plant, electrostatic precipitators, turbo generators to produce power, and a cooling system using hydrogen. Transformers are used to step up the voltage from the generators to connect to the grid.

Installed capacity
8. •The planning commission cleared the
project report in Sept., 1976 for
installation of two units each of 110 MW
in first estimated cost of Rs. 143 Crores .
•And finally stage fifth Unit #7 costed
approximately Rs. 961 Crores.
9. COAL:
1.Northern Coal Fields Limited(NCL),
2.South Eastern Coal Fields
Limited(SECL)
• Coal India limited is supply coal from
its coal mines of coal producing
subsidiaries SECL & NCL to Kota
Thermal Power Station through
railway wagons.
• The average distances of SECL, NCL are
800, 950 Kms. respectively.
10. WATER:-
•The source of water for power station is
reservoir formed by Kota Barrage on the
Chambal River.
• In case of large capacity plants huge
quantities of coal and water is required.
11. 2. General Layout & Basic Idea
•The Kota Thermal Power Station is divided into four
main circuits :
1.Fuel and Ash Circuit.
2 .Air and Gas Circuit.
3.Feed water and Steam Circuit.
4.Cooling Water Circuit.
• A control system of station basically works on Rankin
Cycle.
12.
13. (a).COAL HANDLING PLANT
•It can be called the heart of thermal power plant because it
provided the fuel for combustion in boiler.
•Everyday 6 to 7 trains of coal are unloaded at KSTPS.
• Each train consists of 58 wagons and each wagons consists of
50 tones of coal.
• The approximate per day consumption at KSTPS is about
18000 metric tones.
14. • The whole transportation of coal is through
conveyor belt operated by 3-Ø Induction motor.
• It costs approximate 4.5 crores of rupees per day
including transportation expenses.
•The coal handling plant can broadly be divided into
thre sections.
1) Wagon Unloading system.
2) Crushing System.
3) Conveying System.
15. (b) ASH HANDLING PLANT
• This plant can be divided into 3 sub plants as follows:-
1)Fuel and Ash Plant.
2)Air and Gas Plant.
3)Ash Disposal and & Dust Collection Plant
USES ASH:
1.Manufacturing of building materials.
2.Making of concrete.
3.Manufacturing of pozzuolana cement.
4. Road construction
16. (C). ELECTRO-STATIC PRECIPITATOR
•As far as air pollution is concerned now a days various
flue gases filter are there in service.
•
•These filters are E.S.P. Fabric filter high efficiency
cyclone separations and sitelling room.
•where the particle size vary from 0.75 microns to 100
micron use gradually use E.S.P. to purify the flue gases
due to its higher efficiency & low running cost etc.
17. 6.TURBO GENERATOR
THEORY :-
•TURBO GENERATOR manufactured by B.H.E.L.
• The generator stator is a tight construction, supporting &
enclosing the stator windings, core and hydrogen coolers.
• The generator is driven by directly coupled steam turbine
at a speed of 3000 r. p. m. the Generator is designed for
continuous operation at the rated output.
• The source of excitation of rotor windings is thyristor
controlled D.C. supply.

19. Main parts of generator:-
(a)STATOR:-
STATOR FRAME:-
The stator frame of welded steel frame construction.
STATOR CORE:-
•It is built up of special sheet laminations and whose assembly is supported by a special
guide bass.
STATOR BARS:-
•Stator bars are manufactured as half bars, For an equal length along the bar.
STATOR WINDINGS:-
•Stator windings are double star layers , lap wound, three phase, short pitch type.
• Phases are connected to form a double star winding.
TERMINAL BUSHINGS:-
• The conductor of Generator terminal bushing having hollow copper tubes with Copper
brazed at the ends to avoid leakage of hydrogen.
BEARINGS:-
Generator bearings have electrical seats of consists of steel bodies with removable steel
pads.
HYDROGEN COOLERS:-
•Three Hydrogen Coolers each comprising of two individual units are mounted inside the
stator frame.
21. 4.COOLING SYSTEM
a) GENERAL:-
•In KSTPS hydrogen cooling system is employed for generator cooling.
• Hydrogen is used for cooling medium primarily because of its superior cooling
properties & low density.
• Thermal conductivity of hydrogen 7.3 times of air.
• Its ability to transfer heat through forced convection is about 75% better than air.
b)HYDROGEN DRYERS:-
•Moisture in this gas is absorbed by silica gel in the dryer as the absorbed gas passes
through it.
•The silica gel is reactivated by heating.
22. 10.TRANSFORMER
•Transformer is a static device which is used to change the voltage level keeping the power and frequency same.
•In the plant transformer is one of the most important equipment.
•It is located in between the main plant and the switchyard. The main transformers installed in the transformer yard are:
•GENERATOR TRANSFORMER (GT – A):-
It steps up the voltage from 16.5 KV to 220 KV. It connects the plant with the 220 KV switchyard.
•GENERATOR TRANSFORMER (GT – B):-
It steps up the voltage from 16.5 KV to 400 KV. It connects the plant with the 400 KV switchyard.
•STATION TRANSFORMER (ST):-
It is a step down transformer with 50 MVA capacities. It is used to step down 220 KV from the grid to 6.9 KV.
•AUXILIARY TRANSFORMER (UAT):-
It is a step down transformer with 20 MVA capacities. It steps down the voltage from 16.5 KV to 6.9 KV.
• STATION SERVICE TRANSFORMER (SST):-
It is a step down transformer with 2MVA capacity. It is used to step down from 6.6 KV to 0.4333 KV.
• UNIT SERVICE TRANSFORMER (UST):-
It is a step down transformer with 2 MVA capacity. It is used to step down from 6.6 kV to 0.4333 KV.
