Introduction
 Panipat Thermal Power Station (PTPS) is an
existing 1367.7 MW coal-fired power station
owned by Haryana Power generation
corporation limited (HPGCL).
 The power station is located at Panipat district,
Haryana, India.
 Panipat thermal power station in Haryana
came into existence in the year 1979.
 Coal is supplied from Jharia coal mines,
Dhanbad, Jharkhand.

Introduction(contd.)
 Coal is used as a primary main fuel for
generation of electricity. However light diesel
oil (LDO), heavy fuel oil (HFO) is used in power
as supplementary fuel under emergency
conditions.
 The equipments are supplied by BHEL,
Bhopal.
 There are total eight units in PTPS.
 The ultimate aim to convert chemical energy of
coal or oil to electrical energy.
 In India Thermal Power Plant generates
75.43% of total power generation.

Site selection for Thermal Power Station
Before installing any thermal power plant we have
to focus upon these points:-
Supply of water
Availability of coal
Transportation facilities
Cost and type of land
Nearness to load centers
Distance from populated area
Man power
Ash disposal

How Electricity is produced at Thermal Power station:
• Thermal power station burns fuel and uses
the resultant heat to raise the heat
temperature, which drive the turbo generator.
• Coal is burnt in the pulverized form.
• The pressure energy of the steam produced is
converted into mechanical energy with the
help of turbine.
• The mechanical energy is fed to the generator
where a magnate rotating inside a set of
stator winding and thus electricity is produced.

Coal Handling Arrangement
• In the coal fired plant the raw materials are
coal and water. The coal brought to station by
train is unloaded with the help of wagon
tippler.

9. Coal Handling Arrangement
• After unloading, the coal is send to the crusher house
with help of coal belts.
• The coal which is now reduced to very small pieces, is
sent to coal hopper with the help of conveyer belts.

10. Coal Handling Arrangement
• The raw coal fed to the pulverized or the coal mills
through raw coal feeder. Raw coal feeder basically
regulate the raw coal to pulverize.
• The pulverize coal is sent to the furnace with the help of
Forced draft fan through pulverized coal pipes. This coal
is now burnt.

11. Ash Handling Plant
 Some quantity of the coal results in ash when
the coal is burnt in a boiler furnace. The
function of ash handling plant is:
a) To remove the ash from the furnace.
b) To carry this ash to the storage through
conveyors.
c) To dispose the stored ash.

12. Steam Generating Plant
 Steam generating plant consists of Boiler, Super
heater, Economiser and Air-preheater.
(a) Boiler:
The main function of the boiler is to produce
steam by utilizing the heat from combustion of
coal which converts water into steam at high
temperature and pressure. "A boiler may be
defined as a closed vessel. in which steam is
produced from water by combustion of fuel".
This steam is then passed on to the super
heater.

(b) Super Heater:
The function of super heater is,
I. To remove the, traces of moisture from the
saturated steam given from the boiler.
II. To increase the temperature of steam above
saturation temperature. With this the overall
efficiency increases.
The steam outlet from the boiler is in wet form.
So the super heater is used to make the steam
towards 100% dry saturated steam.

(c) Economiser:
The function of economiser is to:
I. Absorb the heat from outgoing flue gases
II. Increase the temperature of the feed water
coming from the condenser and gives the
heated water to the boiler. With this the
efficiency of boiler is raised and the fuel
consumption is also saved.

(d) Air-preheater:
The function of the air-preheater is to recover
some of the heat from the flue gases. Therefore,
the air is passed through the preheater before it
is passed to the inlet of the forced draught fan
so that it gets preheated and with this
condensation of flue gases and corrosion of air
preheater is prevented. This increases the boiler
efficiency and air temperature.

20.  The water comes through the pipe lines in
thermal power plant .
 In Panipat thermal power plant the source of
water is Satluj yamuna link canal.
 At first the water is chlorified by the use of
chlorine in DM plant.
 Then we make the water insulated and make it
for usual purpose and send it to boiler for further
purpose.

21. Turbine
 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.
 The turbine consists of three stages: high
pressure, low pressure and intermediate
pressure.

22. Turbine
 The turbine consists of three stages- high
pressure, low pressure and intermediate
pressure. It has a shaft with a wheel mounted
with blades. Steam enters at 540°c temp.

23. Generator
 The shaft is coupled with generator. The
generator converts possessed by rotating shaft
to electric energy by Faraday’s law held windings
are exerted by the power exciter.
 Shaft of generator rotates at 3000 rpm. This
generator produced 15.75KV electricity of
power.

24. Condenser
 Condenser is a device which is used to convert a
substance from its gaseous to its liquid state.
 The rest steam obtained from the exhaust is
condensed back in their water form for reuse
purpose.

25. Cooling Tower
 Cooling towers are heat removal devices used to
remove the waste heat to the atmosphere.
Cooling towers either use the evaporation of
water to remove process heat and cool the
working fluid. May 23, 201725

26. How water is cooled in a cooling tower
 Cooling tower is made to fall through a height of
15m in the path of water till its comes down
restriction at different elevation are made so that
the water till looses the heat to the air
surrounding it and itself gets cooled the hot air
goes up and the cold air enter from the bottom to
maintain the cycle.
 The height of cooling tower is 140m.
 It is made this types because hot air does not
pollute the surrounding atmosphere.

27. Chimney
 A chimney is a structure for venting hot gases or
smoke from a boiler, furnace or fireplace to the
outside atmosphere.

28. Switchyard
 A switch yard is a part of a distribution &
transmission system.
 Switchyard transform voltage from high to low,
or the reverse, or perform any of several other
important functions.
