3. INTRODUCTION OF THE THERMAL
POWER PLANT
It was established in 1983.
It is located at the left bank of the CHAMBAL River at the
upstream of KOTA BAIRAJ.
1st & 2nd units are of 110 MW each.
3rd ,4th &5th units are of 210 MW .
6th & 7 unit of 195 MW.
Total generation capacity
(110+110+210+210+210+195+195) =1240 MW
Favorable condition
Abundant quantity of clean cooling water.
Good transport facility
Concentration of load in Kota region due to large
number of industries.

8. Coal Handling Plant
Coal handling plant section
• Wagon unloading system
• Crushing system
• Conveying system

9. Wagon unloading system
 Unload the coal from
wagon to hopper with
the help of wagon
Tripler.
 Hopper allows to pass
coal pieces ≤ 200mm
 From hopper coal fall
on vibrator which is
supported by roller.

10. Conveying system
 Belt are used to convey coal
from coal handling plant to
furnace.
 Specification:-
 Belt width : 1400mm
 Speed : 2.2m/sec
 Total install power : 360kw
 Capacity : 1350/750 ton/hr
 No. of conveyor: 38

11. Crushing system
 CRUSHER HOUSE:- It
consists of crushers which
are used to crush the coal
to 20 mm size.
 Two types
 Primary crusher
o Rail crusher
o Rotary breaker
 Secondary crusher

12. Boiler
 It is a closed vessel in which water under pressure is
converted into steam.
 Hot water or steam used to transfer heat to a process.
 A boiler is always designed to absorb maximum
amount of heat released in process of combustion.
 Furnace:- It is primary part of boiler where the fuel is
burnt to liberate the heat energy.
Chemical Thermal
Energy of Energy by
fuel combustion

14. Super heater
 Super heater consists group of tubes.
 The tubes are heated by the heat of combustion
gases during their passage from furnace to
chimney, so the temperature increased.
 Super heater remove the moisture from the steam
leaving from the boiler tubes.

15. Steam Turbine
 It is a machine in which a
shaft is rotated steadily
by reaction of steam, air
upon blades of a wheel.
 When Steam is used
then it is called steam
turbine.
 It works on Modified
Rankine cycle.

16. Economizer
 Economizer is a device which recover
the heat from the flue gases on their
way to chimney.
 It increases the 10-12% efficiency of the
plant.

17. GENERATOR
•An electrical generator is a
machine which converts
mechanical energy into electrical
energy through electro
mechanical energy conversion .
•The generator is driven by
directly coupled steam turbine at
a speed of 3000 r.p.m.

18. Water Treatment Plant
 Pressure filter removes
undisclosed impurities from
raw water.
 Carbon filter removes excess
chlorine from clarified
water.
 D.M. plant removes dissolved
impurities from clarified
water.
 Conductivity ,pH & silica
content of this water must be
checked time to time.
 D.M. water must be in the
ratio of 1:8

19. Ash Handling Plant
 In thermal plants 25%
is furnace bottom ash
and 75% is pulverized
fuel ash.
 Electrostatic
Precipitator is used in
ash handling plant to
remove fly ash.
