5. WORKING PRINCIPLE
5
 1-4 : Water is pumped into the boiler at high pressure.
 4-5 : Water is converted into steam at constant pressure.
 5-7 : Expansion of steam in the steam turbine.
 7-1 : Rejection of heat into the condenser.

6. COAL HANDLING PLANT
It consist three parts
 Wagon unloading system
 Conveying system
 Crushing system
8700 tons coal is required
per day for each unit.
Coal is supplied from Parsa
kanta mines Chhattisgarh.

8. BOILER
8
Water is converted to generate steam
Types
1.Water tube boiler
2.Fire tube boiler
A boiler is always designed to absorb
max amount of heat released in process
of combustion.
FD fan:-To supply air for combustion of
fuel in furnace.
ID fan:-For sucking out flue gases and
discharge to atmosphere.

10. eCONOMISER
10
 It is a heat exchanger
device that heats up fluids
or recovers residual heat
from the combustion
product.
 It improves the efficiency
of plant 10-12%.
 Temperature : 315° C

11. STEAM TURBINE
11
 It is a machine in which
shaft is rotated by impact
or reaction of steam on
blades of turbine.
 When Steam is used then
it is called steam turbine.

16. Cooling towers
• The two cooling towers of the
facility are 202 metres tall and the
tallest in the world.
• A cooling tower is a heat
rejection device which extracts
waste heat to the atmosphere
through the cooling of a water
steam to a lower temperature.

17. Electrostatic precipitator
17
 ESP is mostly used for
removing the suspended
particles from the flue
gases.
 Consists of two electrodes
• Emitting Electrode
• Collecting Electrode
 The motor operated
hammer is used for
removed deposited
particles.

18. Ash Handling Plant
Electrostatic Precipitator is
used in ash handling plant to
remove fly ash.
Use of ash
• Manufacturing of building
materials.
• Making of concrete.
• Manufacturing of cement.
• Road construction etc.

19. TRANSFORMER
19
It is a device that transfers
electric energy from
one alternating-
current circuit to one or
more other circuits, either
increasing (stepping up) or
reducing (stepping down)
the voltage.
Various Transformers at
KaTPP
• Generating Transformer
• Unit Auxiliary
Transformer
• Station Transformer

20. SWITCHYARD
20
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 Transformer
• Voltage Transformer
• Capacitive Voltage Transformer
• Bus Bar
• Isolators
• Insulators
• Circuit Breakers
• Protective Relays
