Kota Super Thermal Power Station (KSTPS) is located in Kota, India and has a total installed capacity of 1240 MW generated across 7 units. It uses bituminous coal to power steam turbines that drive electricity generators. The main components include the coal handling plant, boiler, steam turbine, generator, and ash handling plant. Coal is delivered by rail, crushed, and conveyed to the boiler which converts it to steam to spin the turbine and generate electricity.

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.
