3. Presentation Outline
• PTPS....... A Brief Overview
• PTPS……. Vision, Mission &
• Achievements
• Thermal Power Plant…….An Overview
• Operation In Thermal Power Plant
• Instrumentation In Thermal Power Plant

4. Patratu Thermal Power Station
• Panipat Thermal Power Station(PTPS)
is governed by Haryana State Electricity
Board.
• Located at about 10 KMs away from
• Panipat on Panipat-Assandh road near
• the village Assan.
• The total installed capacity at P.T.P.S is
• 4*110 MW + 2*210 MW + 2*250 MW
• (1360 MW).

5. PTPS – Vision & Mission
● Vision
To become a modern world class integrated
power generation company, powering
Haryana’s growth on all fronts by maximizing
generation from existing plants".
● Mission
Embarked on a mission to establish itself as a
modern, growth oriented organization and to
make its presence felt in the country’s dynamic
power sector.

6. Thermal Power Plant
• Thermal Power Stations require a number of equipments
performing a number of complex processes with the
ultimate aim to convert chemical energy of coal or oil to
electrical energy.
• This involves the generation of steam in the boiler by
burning coal.
• The steam in turn drives the turbine. The Turbo Generator
coupled with the turbine produces electricity which is
stepped up with the help of transformers and is fed into
grid station through transmission lines.

7. Basic Idea of Electricity
Generation
Coal is unloaded by electric traction system at Coal Yard
Coal is crushed to finer pieces of order 20 mm
Pulverization of Coal
Coal is send to furnace with the help of FD fan
Steam is generated at 540°C and 135 kg/sq.m
Steam is send to Super heater
Superheated steam is send to turbine
Production of Electricity by the generator coupled with

10. Instrumentation In Thermal Power
Plant
When the balance is disturbed, all the process variables deviate
from their normal valves thus creating the necessity for the
following:-
i)Instruments : To measure and indicate the amount of
deviation.
ii)Automatic Control: To correct the deviation and bring back
system to normal
iii) Annunciation : To warn about the excessive deviations, if
any.
iv) Protection : To isolate the equipments process from
dangerous operating conditions cause due to such excessive
deviations.

11. SELECTION CRITERIA OF
INSTRUMENTS
• Required accuracy of measurement
• Range of measurement
• The form of final data display required
• Principle of working
• Cost
• Calibration and repair facilities required/available
• Layout restrictions
• Maintenance requirements/availability

12. Temperature
The degree of hotness and coldness measured
on the definite scale.
• Methods of Temperature Measurement
• Resistance Temperature Detector(R.T.D)
• Thermocouple

13. Resistance Temperature
Detector
• Resistance of certain metals changes as the
temp. changes as per formula given below :-
Rt=Ro(1+wt)
• Where Rt=Resistance at temp. to be measured.
Ro=Resistance at 0 degree C.
w=Temp. coefficient of res. Thermometer metal
t=Temp. to be measured.
• Mainly three metals copper, nickel and platinum
are used as RTD.

14. Thermocouple
• It consists of a pair of wire of different materials.
• Wires are joined at both ends one junction is
kept at a high temp.called hot junction and the
other is kept at a fixed at lower temp.called cold
junction. Due to which emf is setup in the ckt
known as Thermo emf.

15. Pressure
Units for pressure measurement are Newton/m2
, Kg/cm2, mm of water column & mm of mercury
column.
• Devices for Pressure Measurement
• Bourden Tube Pressure Gauge
• Manometer
• Vacuum Gauges

17. ENVIRONMENTAL ISSUSE
AND
CONCERNS
• FLY ASH UTILIZATION:
Total dry flash generation from PTPS is about 18.25
lakh per annum and 6.25 tonne from unit 7 and 8.
In response to the above amount various
firmshave
submitted their offers:
M/s. J. P. Associates Ltd.
M/s Acc. Ltd.
M/s J. K. cement Ltd.

18. *BASIC COMPONENT*
• Generator
• Steam Turbine
• Boiler
• Electrostatic Precipitator
• Power X-mer
• Cooling Tower
• Switch Yard

19. *STEAM TURBINE*
With the use of boiler and then Steam Turbine
makes the plant efficiency better.
The Steam Turbine comprises of one High
Pressure Turbine and one Low Pressure
Turbine.

21. *BOILER*
• Water tube boiler is used in this plant. Steam
pressure at inlet is 102 kg/cm² & steam temp.
at inlet is 535˚C. In this boiler , water is flow in
the tube in furnace . Steam produces in tube
& it collect in a drum which is situated on the
top of boiler . Then steam goes to turbine.
