INTRODUCTION:-
 NTPC is a Maharatna Company .
 Approved capacity – 2600MW.
 Installed capacity – 2600 MW.
 Location – Korba , Chhattisgarh.
 Approved investment – 2448.49 crore.
 Coal source – Kusmunda block , Gevra Mines.
 Water source – Hasdeo River.
 Beneficiary states - Madhya Pradesh,Chhattisgarh,Maharashtra,Gujrat, Goa.
4
 Sources of coal in NTPC - Kusmunda block & Gevra
mines.
 Resources of coal – By road and by trains.
 Coal size – 200mm approx.
5
 a pulverize mill is used to pulverize
coal for combustion in the steam-
generating furnaces of fossil fuel power
plants.
 The crushing process of coal after that there
size is <20mm.
6
 Coal dust is a fine powder of coal.
 In this process after coal size is 0.6mm.
7
 A furnace is a device used for high-
temperature heating.
 The heat energy to fuel a furnace may be
supplied directly by fuel combustion, by
electricity such as the electric arc furnace, or
through induction heating in induction
furnaces.
8
 A boiler is a closed vessel in which water or
other fluid is heated.
 Boilers produce steam to be used
at saturation temperature.
9
 A turbine in which a high-velocity jet of
steam rotates a bladed disc or drum.
 A steam turbine is a device that
extracts thermal energy from
pressurized steam and uses it to
do mechanical work on a rotating output
shaft.
10
 How does an Alternator work ?
 Alternators are the workhorse of the power generation
industry .It is capable to generate AC power at a specified
frequency. They are also referred as Synchronous
generators. This video gives a detailed and illustrative
introduction on working of alternators.
 Electricity is produced in alternators by electromagnetic
induction. To generate electricity in a coil either the coil
should rotate with respect to a magnetic field or a
magnetic field should rotate with respect to the coil.
11
 A power station, also referred to as
a generating station,power plant,
powerhouse, or generating plant, is an
industrial facility for the generation of
electric power. Mostpower stations contain
one or more generators, a rotating machine
that converts mechanical power into
electricalpower.
12
 The giant, jug-shaped cooling towers you see
at old power plants make the turbine more
efficient. Boiling hot water from the steam
turbine is cooled in a heat exchanger called a
condenser.
13
 The electricity travels out of the generator to
a transformer nearby.
14
 Electricity loses some of its energy as it
travels down wire cables, but high-voltage
electricity loses less energy than low-voltage
electricity. So the electricity generated in the
plant is stepped-up (boosted) to a very high
voltage as it leaves the power plant.
15
 When the Coal combustion takes place in the
boiler, some part of the coal remains unburnt
and that un-burnt particles are called the
ash.
16
17
 Use of helmet
 Do not touch any equipment without permission
 Use of shoe when going to inside of plant
 Economical for low initial cost other than any
generating plant.
 Land required less than hydro power plant .
 Since coal is main fuel and its cost is quite cheap
than petrol/diesel so generation cost is
economical.
 There are easier maintenance.
 Thermal power plant can be installed in any
location where transportation & bulk of water are
available.
18
 The running cost for a thermal power station
is comparatively high due to fuel ,
maintenance etc.
 Large amount of smoke causes air pollution.
The thermal power station is responsible for
Global warming.
 The heated water that comes from thermal
power plant has an adverse effect on the lives
in the water and disturbs the ecology.
 Overall efficiency of thermal power plant is
low like less 30%.
