### kstps summer training 36 slides

1. 1. A Seminar on Practical Training Taken at KOTA SUPER THERMAL POWER STATION During 21th July 2008 to 4th Augest 2008 By DIVESH KACOLIA IV B.E. VII Sem. Electrical Engg. in the partial fulfillment for award the degree of Bachelor of Engineering From University of Rajasthan, Jaipur Submitted toDepartment of Electrical Engineering Jaipur Engineering College & Research Center Session 2008-2009
2. 2. CONTENTS 1. INTRODUCTION ABOUT KOTA SUPER THERMAL POWER STATION 2. ENERGY GENERATED IN KSTPS 3. ELECTRICITY GENERATION AT KSTPS 4. COAL HANDING PLANT 5. PULVERISING PLANT 6. BOILER 7. TURBINE 8. DC SYSTEM 9. ECONOMISER 10. GENARATOR 11. TRANSFORMER 12. CHIMNEY 13. COOLING TOWER 14. D.M. WATER PLANT 15. WATER TREATMENT PLANT 16. CONTROL ROOM 17. PROTECTION 18. CONCLUSION
3. 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. 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
5. 5. ELECTRICITY GNERATION AT KSTPSTHERMAL POWER STATION BURNSTHE FUEL AND USE THE RESULTENTHEAT TO RAISE THE STEAM WHICHDRIVES THE TURBO GENERATOR
6. 6. EXHAUT COAL STORAGE FORCED DRAFT FAN COAL C HANDLING H I M AIR NASH AIRSTORAGE ASH HANDING BOILER PREHEATER E Y FURNANCE SUPER HEATER RAW WATER TANK FWH CONDESER TURBINE CKT BREAKER
7. 7. 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.
8. 8. COAL HANDLING PLANT Raw coal from To KSTPS Wagon Bharat coking from Gudla Tripler coal ltd (MP) via a single line track Coal mills VibratorsBoilers Raw Coal Feeder Crusher house Junction (20mm x 20mm)Bunkers tower Stock yard
9. 9. 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.
10. 10. BOILER BOILER IS A PLACE THE WATER IS BEING CONVERTED INTO STEAM WITH BURNING OF COAL. WATER TUBE BOILER USED IN KSTPS.
11. 11. 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
12. 12. Cont.. Steam turbine is used at KTPS PIC 1: Closer look of steam turbine at KTPS.
13. 13. DC SYSTEMDC POWER CAN BE STORED IN A BETTERYAND USE IN EMERGENCY.EMERGENCY LIGHTNING,CONTROL & RELAYEQIPMENT,COMMUNICATION ETC.METHOD OF OBTAINING DCRECTIFIER * WHICH CONVERT AC INTO DC * BASIC COMPONENTS ARE DIODE CLASSIFICATION *HALF WAVE RECTIFIER *FULL WAVE RECTIFIER
14. 14. ECONOMISER FLUE GASES FEED WATER OUTLET FEED WATER INLET FLUE GASESFLUE GASAE COMING OUT OF THE BOILER CARRY LOTOF HEAT. AN ECONOMISER EXTRACTS A PART OFTHESE HEAT FROM THE FLUE GASES AND USES FOR HEATINGFEED WATER AND IMPROVERS EFFICIENCY OF PLANT.
15. 15. Cont..Efficiency increased by the Economiser 33 32.5 32 31.5 Without 31 Economiser 30.5 With 30 Economiser 29.5 29 28.5 1st Qtr
16. 16. 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.
17. 17. 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
18. 18. CHIMNEYA SINGLE CHIMNEY OF 180M HEIGHT WITH TWOSEPRATEFLUES FOR THE TWO UNIT EACH OF 110MW ISPROVIDED. SIMILARLY ANOTHER CHIMNEY WITH THREE SEPARATEFLUES IS ALSO PROVIDED FOR ANOTHER THREE UNITSOF 210 MW EACH AND ONE CHIMNEY FOR THE SIXTHUNIT OF 195MW IS ALSO CONSTRUCTED IN 2003.
19. 19. 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.
20. 20. 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.
21. 21. WATER TREATMENT PLANTTHE PRINCIPLE PROBLEM IN HIGH PRESSUREBOILER ARE CORROSION AND STEAMIMPURITIES.THESE IMPURITIES FORMDEPOSITE OVER TURBINE BLADES ANDNOZZELES.CORROSION COSTS POWER STATION CRORESRUPEES IN REPAIR.
22. 22. 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
23. 23. CONTROL ROOMIN CONTROL ROOM VARIOUSCONTROLS ARE PROVIDED.SIMULTANEOUELY VARIOUS AREMADE.VARIOUS RELAYS AREPROVIDED HERE.THE CONTROL ROOM HAS A SET OFPARAMETERS PANEL FOR INDICATINGAND RECORDING VARIOUS DATAS.

25. 25. PROTECTION 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
26. 26. 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.
