3. INTRODUCTION
KALISINDH SUPER THERMAL POWER STATION(KATPP) is
located in Jhalawar district , Rajasthan.
KATPP has installed capacity of 1200MW.
The first unit is commissioned in 2014 March with an
installed capacity of 600 Megawatt. Similarly the
second unit is commissioned in 2014 June.
Source of water for the plant is from Kalisindh Dam.
Primary Coal source for the plant will be from Paras
east and Kanta Basin coal blocks in Chhatisgarh State.
Revised cost of the project is Rs 9479.51 Crores.
4. WORKING PRINCIPLE OF THERMAL POWER
PLANT
1. Water is pumped into the boiler
at high pressure.
2. Water is converted into steam at
constant pressure.
3. Expansion of steam into steam
turbine.
4. Rejection of heat into the
condenser.
6. COAL HANDELING PLANT
It consist of three parts
• Wagon unloading system
• Conveying system
• Crushing system
8700 tons of coal required per day for each unit.
Coal is supplied from Parsa and Kanta mines from Chhattisgarh.

8. BOI
LER
A Boiler or Steam generator is a closed vessel to which
water under pressure, is converted into steam.
It is one of a major component of a thermal power
plant
Always designed to absorb maximum amount of heat
released in the process of combustion
Types of boilers
•Water tube boiler
•Fire tube boiler
FD fan – To supply air for combustion of fuel in
furnace.
ID fan – For sucking out gases and discharge to
atmosphere.
9. ECONOMIS
ER It is a heat exchanger device that
heats up the fluid or recover residual
heat from the combustion product
It improves the efficiency of plant 10-
12%
Temperature : 315 C
10. STEAM TURBINE
A steam turbine is a mechanical device that extracts thermal energy from
pressurized steam , and converts it into mechanical energy.
In a thermal power plant generally three turbine are used to increase the efficiency.
High pressure turbine (HPT) : The superheated steam is directly fed to this
turbine to rotate it.
Intermediate pressure turbine(IPT) : The output from the HPT is reheated in a
reheater and used to rotate IPT.
Low pressure turbine (LPT) : The exhausted steam from IPT is directly fed to rotate
the shaft of LPT.
All the turbines are connected to a single shaft which is connected to the generator.
12. TURBINE SPECIFICATION
No. of casings
Two Casings (HP/IP Turbine - LP
Turbine)
Three Casings (HP/IP Turbine - LP
Turbine ×2)
Three Casings (HP Turbine - IP Turbine
- LP Turbine)
Four Casings (HP Turbine - IP Turbine -
LP Turbine×2)
Five Casings (HP Turbine - IP Turbine -
LP Turbine×3)
Output Up to 1,200 MW
Main steam conditions Up to 28.0 MPa / Up to 600°C
Reheat steam conditions Up to 630°C
Revolutions per minute
3,000 min-1
(50 Hz) / 3,600 min-1
(60
Hz)
13. GENERATOR
Generator has a magnetic field, it has a stator and a rotor. When steam turbine rotates the
generator shaft, it creates a magnetic field and produce electricity from electro-
mechanical energy conversion.
The generator is driven by directly coupled steam turbine at a speed of 3000 rpm.
The generated voltage will generally from 11KV to 33KV max.
The generated voltage is stepped up by connecting Step up transformer and is also used for
auxiliary purpose.
14. ELECTROSTATIC PRECIPITATOR(ESP)
An electrostatic precipitator (ESP) is another very important to filtrate the air. Due to
combustion of fuel, flue gas consist of ash particles ,dust, smoke , foreign particles which need
to be removed to reduce air pollution.
It create a strong electric field to remove all unwanted particles from the flue gas.
15. Cooling Towers
The two cooling towers of the facility are 202 meters tall and the tallest in the world.
The circulating water picks up the heat from turbine exhaust and becomes heated. Hence this
heated cooling water needs to be cooled to complete the cycle.
The water is cooled in cooling tower through circulating pump.
Heat in circulating water is rejected in cooling tower.
There will be around 2% evaporation loss happens in the cooling tower.
There are circulating pumps are used to transfer the water in a closed cycle, from the
condenser to the cooling tower.
16. ASH HANDELING PLANT
Electrostatic precipitator is used in ash handling plant to remove fly ash.
Use of ash :-
• Manufacturing of building material.
• Making of concrete.
• Manufacturing of cement.
• Road construction etc.
17. TRANSFORMER
It is a device that transfers electrical energy from one alternating current circuit to one or more
other circuits. Either increasing( stepping up) or decreasing ( stepping down) the voltage.
Various Transformers at KATPP.
I. Generating transformer.
II. Unit auxiliary transformer.
III. Station Transformer.
18. SWITCHYARD Switchyard is the interconnector between generation
and transmission and the same voltage is maintained in
switchyard.
Switch consists of the following instruments:-
Lightening Arresters
Current Transformers
Capacitive voltage transformers
Bus bar
Isolator
Insulator
Circuit breakers
Protective relays
19. CONTROL PANEL
All the Basic parameter like temperature of steam and air, flow
of water and air, pressure, electricity generation etc. are
controlled in control panel.
Control panel 1 :- Fan control desk.
Control panel 2:- Fuel Control desk.
Control panel 3:- Steam & Water control desk.
Control panel 4:- Turbine Control desk.
Control panel 5:- Generator control desk.
20. CONCLUSION
Coal fired power plant are backbone
of the electricity supply system in
India, generating more than 70 % of
the electric power.
Even if more natural gas -
fueled combined cycle power plants
and more renewable power generation
facilities will be built, a major portion
of electric power will still be
provided by coal - fired power plants.
