The document summarizes the Bokaro Thermal Power Station located in Jharkhand, India. It has three units that generate a total of 630 MW of power. The power station uses coal as its fuel source, which is handled through a coal handling plant and crushed before being fired in the boiler. The boiler then heats water to create high-pressure steam, which spins turbines connected to generators to produce electricity. The steam is reused in the process by passing through a superheater, economizer and condenser before being treated and reused. Ash is removed using an electrostatic precipitator and handled separately. A control room monitors and regulates the entire power generation process.

6. PRINCIPLE of PLANT

7. 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

8. Coal Handling Plant

9. 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

10. 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

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.

13. 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.

14. 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.

15. 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.

16. •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.

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.
