PRESENTATION OF INDUSTRIAL
TRAINING ON
THERMAL POWER PLANT
AT NTPC, SHAKTINAGAR
Under guided by:- Submitted by:-
Miss. SAKSHI SHARMA PANKAJ
CHAUDHARY.
EEE -7th sem.
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.
