3. INTRODUCTION
• A thermal power station is a power plant in which heat
energy is convert to electrical power.
• Kota super thermal plant station (KSTPS) was established
in 1983.
• Total generation capacity of KSTPS is 1240 MW.
• It is located at the left bank of the CHAMBAL River at the
upstream of KOTA BAIRAJ.
• Bituminous Coal is used as fuel.
• Calorific value of coal is 3,300 k.cal/Kg.
• Coal India Limited supplies coal to KSTPS.

5. GENERAL LAYOUT OF KSTPS

6. MAIN PARTS OF KSTPS
Coal Handling Plant.
 Boiler.
 Ash Handling Plant.
 Steam Turbine.
 Electricity Generator.
 Cooling System.
 Transformer.
 Control Panel.

7. COAL HANDLING PLANT
Coal handling plant section:
1. Wagon Unloading System.
2. Crushing System.
3. Conveying System.

8. 1. Wagon Unloading System
o Unload the coal from wagon to
hopper with the help of wagon
Tripler.
o Hopper allows to pass coal
pieces < 200 mm.
o From hopper coal fall on
vibrator which is supported by
roller.

9. 2. Crushing System
o CRUSHER HOUSE:-
It consists of crusher
which are used to crush the coal to
20 mm size.
o Two types-
 Primary crusher
• Rail crusher
• Rotary crusher
 Secondary crusher

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

11. 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.

12. 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

13. 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 work on Modified Rankine cycle

14. ECONOMIZER
 Economizer is a device which
capture the waste heat from
boiler fuel gases and transfer
it to the boiler feedwater.
 This raises the temperature of
the boiler feedwater.
 It increases the 10-12%
efficiency of the plant.

15. 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.

16. 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

17. 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.
