Barauni Thermal Power Station (BTPS) is a 320 megawatt coal-fired power plant in Begusarai, Bihar, India. It was established in 1962 through Russian collaboration. BTPS currently has 7 generating units, with 2 operating and producing 220 MW total, while units 5 and 7 undergo renovation. Coal is supplied from local mines and the plant is expanding to increase capacity to 500 MW in the next 5 years. BTPS converts the chemical energy of coal into electrical energy through steam turbines, and generates power for distribution in North Bihar.

2. ABOUT B.T.P.S
Barauni Thermal Power Station is an
existing 320 megawatt coal-fired power
station owned by Bihar State power
generation company limited (BSPGCL).
The power station is located at
Begusarai district, Bihar, India.
 Barauni thermal power station in Bihar
came into existence in association with
the Russian collaboration in the year
1962.

3. coal is supplied from Rajmahal coal
field and Urma Pahari
tola,Jharkhand.
Currently two new units VIII and IX
are under construction which will
increase the power output by
500MW.
The equipments are supplied by
BHEL , Bhopal.
The electricity generated here is
sold to North Bihar Power Holding

4. GENERATION UNITS AT B.T.PS
There are total seven units in B.T.P.S
Two units are currently working
producing total o/p of 220 MW.
Unit no. V and VII are undergoing
renovation and modernization.
The capacity of plant will be increased
to 500 MW in next 5 years.

5. Thermal power plant
A generating station which converts heat energy of coal
combustion into electrical energy.

7. Working principle

8. LAW OF CONSERVATION OF ENERGY
Chemical energy of fuel
Heat energy in furnace
Heat energy of medium water
Kinetic energy of turbine rotor
Electromotive force
Electricity generation

9. Division of a thermal power plant
Coal Handling Plant
Water Treatment Plant
Fuel and Ash Plant
Feed Water and Steam Plant
Cooling Water Plant

10. Constituents of thermal power plant
Steam generating equipment
Condenser
turbines
Cooling towers
Electrical equipments

11. Steam generating equipment
Boiler
Boiler furnace
Superheater
Economiser
Air preheater

12. condenser
It condenses steam at exhaust
of turbine.
It creates very low pressure at
the exhaust of turbine which
helps in converting heat energy
of steam into mechanical energy
in prime mover.
The condensed steam can be

13. turbines
It is used as prime mover to generator.
Three types of turbine are used :
1.HP turbine
2.IP turbine
3.LP turbine

15. Electrical equipments
Generator : To generate electricity
Transformer : For required voltage
Switch yard : Onward transmission of
powers

16. Why coal as a fuel
Coal can provide usable energy at a
cost of between 12 to 15 % compared to
oil and natural gas, and coal prices are
relatively stable.
Coal is inherently higher polluting and
carbon intensive than other energy
alternatives. However coal is so
inexpensive that one can spend quite a
bit on pollution control, and still maintain
coal’s competitive position.

17. Types of water required
DEMINERALISED WATER :
BOILER
SOFTEN WATER : COOLING
AND GENERAL SERVICE
DRINKING WATER : DOMESTIC
PURPOSE
UNTREATED WATER : ASH
HANDLING,COAL HANDLING
AND FIRE FIGHTING

18. observations
B.T.P.S has a very good working
environment.
B.T.P.S is very sincere about
cleanliness and hygiene.
It has got a Technical training
centre with very good learning
environment.
Staff is excellent and supportive
and always ready to help.

19. conclusion
It is third largest thermal power
plant of Bihar.
It generates 210 MW electricity and
after completion of extension
project it will produce 500 MW
electricity.
It is major contributor of electricity
to 7 districts of north Bihar.
