2. INTRODUCTION
• In Kota Super Thermal Power Station electricity is generated.
• The project was proposed by Central Electric Authority of
India in April, 1973.
• The project was revised in 1975 and approved in Sep., 1976.
• At first two units were installed each producing 110 MW of
power.
• The first estimated cost was Rs. 143 Crores.

7. COAL HANDLING PLANT
The coal is brought to the
KSTPS through rails.
There are fourteen tracks in
all for transportation of coal
through rails.
Everyday 3 to 4 trains of coal
are unloaded at KSTPS.
The approximate per day
consumption at KSTPS
is about 3074 tones.
8. WAGON TRIPLER
Wagons From the
coal yard come to the
tippler and are emptied
here.
The process is
performed by a Slip ring
motor of rating 55KW,
415V, 1480 RPM.
This motor turns the
wagon by 150 degree
and coal falls directly on
the conveyor through
vibrators
9. WATER TREATMENT PLANT
The principle problem in high pressure boiler are corrosion
are steam impurities.
These impurities form deposit over turbine blades and
nozzels.
Corrosion costs power station crores in repair
10. BOILER
Temperature of Super
Heated Steam – 540’c
Pressure-144 kg/cm*cm
• Boilers are used for
electrical power
generation, heat energy is
released from the
combustion of fuels.
• BHEL make direct fired
natural circulation
balanced draft tube
boilers are used here,
having capacity of 375
tones/hour and efficiency
of 86.6%.
12. 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.
15. TRANSFORMER
Transformer is a static device which
is used to change the voltage level
keeping the power and frequency
same.
In the whole plant there are about 83
transformer installed at various
places to operate the auxiliaries.
Main transformers, which are
necessary:
1. To step up the generated voltage.
2. To supply power to the
auxiliaries from the generator.
3. To start the plant by taking the
supply from the grid
16. Fly ash (80%).
Used for making bricks.
Cement.
Bottom ash (20%)
Used to improve fertility.
Roads.

17. In KSTPS hydrogen
cooling system is
employed for generator
cooling.
Hydrogen is used because
of its superior cooling
properties & flow density.
Thermal conductivity of
Hydrogen 7.3 times of air.
Water Cooling is also used
to cooling system.
18. Two 220 KV bus
bars have been
provided in switch
yard and are inter-
connected through
a bus coupler
