Presentation on

barauni thermal power station

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.

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

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.

Thermal power plantA generating station which converts heat energy of coal

combustion into electrical energy.

Working principle

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

Boiler furnace

Superheater

Economiser

Air preheater

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

used as feed water to the boiler.

turbinesIt is used as prime mover to generator.

Three types of turbine are used :

1.HP turbine

2.IP turbine

3.LP turbine

Electrical equipments

Generator : To generate electricity

Transformer : For required voltage

Switch yard : Onward transmission of

powers

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.

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

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.

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.
