2. KSTPS Looking at space

4. INTRODUCTION
•At present total installed capacity of KSTPS is 1240 MW.
• KSTPS has received Meritories productivity awards
during 1984, 1987, 1989, 1981 and every year since 1992
onwards.
•finally stage fifth Unit #7 costed approximately Rs. 961 Crores
•Kota Super Thermal Power Station is the first coal based
Electricity Generating station in rajasthan.

7. WATER:-
The source of water for power station is
reservoir formed by Kota Barrage on the
Chambal River.

8. 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.

11. COAL HANDLING PLANT
It can be called the heart of thermal power plant because it
provided the fuel for combustion in boiler.
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 KSTPS through
railway wagons.
• Everyday 6 to 7 trains of coal are unloaded at KSTPS.
• The approximate per day consumption at KSTPS is about
18000 metric tones.

12. 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

13. Unload the
coal from
wagon to
hopper with
the help of
wagon
Tripler.

14. Belt are used to convey
coal from coal handling
plant to furnace.

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. STEAM TURBINE

18. .
TECHNICAL DATA OF TURBINES :-
The main technical data of 110 MW turbine is given below:-
Rated output. : 110 MW.
Economic output : 95 MW.
Rated speed. : 3000 rpm
Direction of rotation viewing from : Clockwise
Rated steam pressure before : 130 atm
stop valve.
Maximum steam pressure before : 146 atm
stop valve.
Rated temperature of steam before : 535oC
the stop valve.
Maximum temperature of steam before : 545oC
the stop valve.
Rated pressure of steam : 31.6 atm
MP Casing.
Rated pressure of steam before : 35 atm

19. Steam Flow
HP Turbine
IP Turbine
LP Turbine
 It convert heat
energy of steam into
mechanical energy
and drive generator.
 It uses the principle
the steam when
issuing from a small
opening attains a
high velocity.

20. 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.

25. 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.

26. •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.
