3. Introduction
LOCATION SAKATPURA,KOTA
K.T.P.S is designed in four stages
STAGE l 2 x 110MW
STAGE ll 2 x 210MW
STAGE lll 1 x 210MW
STAGE lV 1 x 195MW
TOTAL 1045MW

4. ENERGY GENERATED IN KSTPS
 TOTAL CAPACITY =1045MW
 TOTAL GENERATED ELECTRICITY PER HOUR =1045*HR.
=10.45 LACS UNITS
 AMOUNT OF ENERGY GENERATED DAILY =10.45*24
=250.8 LACS UNITS
 COAL REQUIRED OF ONE UNIT =0.5 KG.
 SO AMOUNT OF COAL(PER DAY) =0.5*250.8*100000 KG.
=125.4 MILLION KG.
 5 TRAINS OF COAL SUPPLY THIS AMOUNT OF COAL DAILY

6. ELECTRICITY GNERATION AT KSTPS
THERMAL POWER STATION BURNS
THE FUEL AND USE THE RESULTENT
HEAT TO RAISE THE STEAM WHICH
DRIVES THE TURBO GENERATOR

9. COAL HANDLING PLANT
 THE COAL FOR RECEIVED FROM BHARAT COKING COAL
LTD. DHANBAD & SOUTH EASTERN COAL FIELD LTD.
BILAS PUR(M.P.) BY TRAIN.FOLLOWING PERMUTATION AND
COMBINATION OF OPERATION ARE POSSIBLE WITH INSTALLED
SYS.
 1. TO TRANSFER ALL CRUSHED COAL RECIVED FROM CRUSHER
HOUSE TO LIVE STORAGE PIPE.
 2. TO TRANSFER PART OF RECEIVED CRUSHED COAL TO PLANT
& TO BALANCE TO STROAGE YARD.
 3. TO DELIVER THE RAW COAL BUNKERS PAR & RECEIVED
CRUSHED COAL MIXED WITH BALANCE COAL FROM THE LIVE
STROAGE PIPE.
 4.TO TRANSFER THE PLANT CRUSHED COAL AT 750T/HR.FROM
THE RECLAIM LIVE PIPE AND SIMULTANEOUSLY STOCK AND
S/RAD.

10. COAL HANDLING PLANT
Raw coal from To KSTPS Wagon
Bharat coking from Gudla Tripler
coal ltd (MP) via a single
line track
Coal mills
Vibrators
Boilers
Raw Coal
Feeder
Crusher house
Junction (20mm x 20mm)
Bunkers tower Stock yard

12. PULVERISING PLANT
 IN MODERN THERMAL POWER PLANTS COAL IS
PULVERISED I.E. GROUND TO DUST LIKE SIZE AND
CARRIED TO THE FURNACE IN A STREAM OF A HOT
AIR.
 ADVANTAGES:-
 THE RATE OF COMBUSTION CAN BE CONTROLLED AND CHANGED
QUICKLY TO MEET THE VARYING LOAD.
 THE PERCENTAGE OF EXCESS AIR REQUIRED IS LOW.
 AUTOMATIC COMBUSTION CONTROL CAN BE USED.
 A WIDE VARIETY OF EVEN LOW GRADE COALS CAN BE USED.

13. BOILER
BOILER IS A PLACE THE WATER IS BEING
CONVERTED INTO STEAM WITH BURNING
OF COAL.
WATER TUBE BOILER USED IN KSTPS.

15. TURBINE
Turbine is a machine in which a shaft is
rotated steadily by impact or reaction of
current or stream of working substance
(steam,air,water,gases etc.).
It convert the PE or KE of the working
substance into mechanical power by
virtue of dynamic action of working
substance

16. Cont..
Steam turbine is used at KTPS
PIC 1: Closer look of steam turbine at KTPS.

17. DC SYSTEM
DC POWER CAN BE STORED IN A BETTERY
AND USE IN EMERGENCY.
EMERGENCY LIGHTNING,CONTROL & RELAY
EQIPMENT,COMMUNICATION ETC.
METHOD OF OBTAINING DC
RECTIFIER
* WHICH CONVERT AC INTO DC
* BASIC COMPONENTS ARE DIODE
 CLASSIFICATION
*HALF WAVE RECTIFIER
*FULL WAVE RECTIFIER

18. ECONOMISER
FLUE GASES
FEED WATER OUTLET
FEED WATER INLET
FLUE GASES
FLUE GASAE COMING OUT OF THE BOILER CARRY LOT
OF HEAT. AN ECONOMISER EXTRACTS A PART OF
THESE HEAT FROM THE FLUE GASES AND USES FOR HEATING
FEED WATER AND IMPROVERS EFFICIENCY OF PLANT.

19. Cont..

20. GENERATOR
GENERATOR IS A M/C WHICH CONVERT
MECHANICAL ENERGY INTO ELECTRICAL
ENERGY.THE GENERATOR HAS STATOR IN
GAS COLINGTH CONSTRUCTION
ENCLOSING THE STATOR WINDING
,CORE,&HYDROGEN COOLERS.

21. TRANSFORMER
 X-MER IS A STATIC DEVICE WHICH STEP UP OR
DOWN THE VOLTAGE WITHOUT ANY CHANGE IN
FREQUENCY.
 THERE ARE VARIOUS X-MER IS USED FOR
VARIOUS PURPOSES.
1.GENERATING X-MER
2.UNIT AUXILARY X-MER
3.INSTRUMENT X-MER
(a) CURRENT X-MER (b) POTENTIOL X-MER
4.CAPACITOR VOLTAGE X-MER

23. CHIMNEY
A SINGLE CHIMNEY OF 180M HEIGHT WITH TWO
SEPRATE
FLUES FOR THE TWO UNIT EACH OF 110MW IS
PROVIDED.
SIMILARLY ANOTHER CHIMNEY WITH THREE SEPARATE
FLUES IS ALSO PROVIDED FOR ANOTHER THREE UNITS
OF 210 MW EACH AND ONE CHIMNEY FOR THE SIXTH
UNIT OF 195MW IS ALSO CONSTRUCTED IN 2003.

25. COOLING TOWER
A COOLING TOWER IS A STEEL OR COCRETE
HYPERBOLIC STRUCTURE HAVING A
RESERVOIR AT THE BOTTOM FOR STORAGE
OF COOLED WATER. WARM WATER IS LED TO
THE TOP. AIR FLOWS FROM THE BOTTOM TO
THE TOP. THE WATER DROPS FALLING FROM
THE TOP COME IN CONTACT WITH AIR, LOSE
HEAT TO THE AIR AND GET COOLED.

27. D.M. WATER PLANT
IN D.M. WATER PLANT THE DE-
MINERIALIZATION OF WATER USED IN
STEAM GENERATION IN BOILER IS
DONE, SO THAT THE IMPURITIES AND
UNWANTED MINERALS IN THAT WATER
MAY NOT CAUSE ANY HARM TO BOILER
AND TURBINE.

28. WATER TREATMENT PLANT
THE PRINCIPLE PROBLEM IN HIGH PRESSURE
BOILER ARE CORROSION AND STEAM
IMPURITIES.THESE IMPURITIES FORM
DEPOSITE OVER TURBINE BLADES AND
NOZZELES.
CORROSION COSTS POWER STATION CRORES
RUPEES IN REPAIR.

29. SPACIFICATION OF SCREEN
WATER PUMPS
PUMP TYPE HORIZONTAL,CENTRIFUGAL,SINGLE STAGE
CAPACITY 275 FT.
POWER 110 H.P.
SPEED 2900 RPM
MOTOR 25 H.P.,159 AMP.,VOLTAGE 415 V.
LUBRICATION GREASE

31. CONTROL ROOM
IN CONTROL ROOM VARIOUS
CONTROLS ARE PROVIDED.
SIMULTANEOUELY VARIOUS ARE
MADE.VARIOUS RELAYS ARE
PROVIDED HERE.
THE CONTROL ROOM HAS A SET OF
PARAMETERS PANEL FOR INDICATING

 DIFERENT TYPES OF PROTECTION CAN BE LISTED AS
 (1)CURRENT OPERATED PROTECTION
 (2)DIFFERENTIAL PROTECTION
 (3)VOLTAGE OPERATED PROTECTION
 (4)IMPEDANCE TYPE PROTECTION
 (5)FREQENCY TYPE PROTECTION

35. CONCLUSION
It was a knowledgeable experience while
taking practical training at KOTA SUPER
POWER THERMAL STATION .
It proved an opportunity for encounter
with such huge machines like tippler
,turbine and generator. But there are few
factors that require special mention.
training proved quite faithful.
