NTPC, the largest power Company in India, was

setup in 1975 to accelerate power development in

the country.

NTPC has installed capacity of 29,394 MW.

Installed Capacity 2000 MW Location Sonebhadra, Uttar Pradesh Coal Source Jayant mine Water Source Rihand Reservoir Beneficiary States UttarPradesh,Uttranchal,

Rajasthan, Punjab, Haryana, Delhi and, Himachal Pradesh, Chandigarh

Unit Sizes Stage - I: 5x 200 MWStage -II: 2x 500 MW

Prime mover coupled to Alternator.

Prime mover is driven by energy obtained from various

sources such as

burning of fuel , pressure of water, force of wind etc.

Fig. Fundamental of generation of Electricity

A generating station which converts heat energy of

coal combustion into electrical energy is known as a

steam power station.

Steam is produced in the boiler by utilizing the heat

of coal combustion. The steam is then expanded in

the steam turbine and is condensed in a condenser to

be fed into the boiler again. The steam turbine drives

the alternator which converts mechanical energy of

the turbine into electrical energy.

Boiler

A boiler is closed vessel in which water is converted

into steam by utilizing the heat of coal combustion.

Steam boilers are broadly classified into following two

types:

(a) Water tube boilers (b) Fire tube boilers

In a water tube boiler, water flows through the tubes

and the hot gases of combustion flow over these tubes.

Water-tube boilers are used for high-pressure boilers

A device which removes last traces of moisture.

It helps in reduction in requirement of steam

quantity.

steam being dry reduces the mechanical resistance

of turbine.

No corrosion at the turbine blades.

Which condenses the steam at the exhaust of

turbine.

It creates a very low pressure at the exhaust of

turbine, this helps in converting heat energy of

steam into mechanical energy in the prime mover.

The condensed steam can be used as feed water to

the boiler.

A steam turbine is a mechanical device that extracts

thermal energy from pressurized steam, and converts

it into mechanical energy.

About 86% of all electric generation in the world is

by use of steam turbines.

Source of coal = Jayant Mines (Madhya Pradesh)

Location of source = Near Singrauli (Madhya Pradesh)

Distance of source from plant = 5kms

Type of coal = D grade

Coal requirement = 25,000 MT/Day

CHP

from track hopper to bunkers

Generally thermal power stations use coal mills

or called coal firing system.

Coal is reduced to fineness (-20mm).

This fine powdered coal is called pulverized

coal and is carried forward to the burner by air

through pipes.

MILLS

SWITCHYARD

Switchyard is considered as the HEART of

power plant.

It is a junction , which carries the generated

power to its destination.

It is basically an open area where many

different kind of outdoor equipments are

located.

Switch yards can be of 400KV, 132KV.
