1. SWAMI KESHVANAND INSTITUTE OF TECHNOLOGY A SEMINAR ON PRACTICAL TRAINING AT “KOTA SUPER THERMAL POWER STATION” SUBMITTED TO:- DEPT. OF ELECTRICAL ENGINEERING SUBMITTED BY:- DEVKINANDAN NAGAR 08ESKEE018

2. KOTA SUPER THERMAL POWER STATION

5. COAL HANDLING PLANT FUNCTION - Automatic feeding of coal to boiler furnace PROCESS - 1) Coal is unloaded from rail wagons in IV unit of KSTPS 2) Coal is sent to crusher where coal is reduced to very small size Consumption of coal/Unit of electricity - 0.6 Kg Consumption/day - 20000 tons/day DEVICES - Wagon Tripler - 5 (32 wagons/hr) 2) Vibration Feeders - Electromagnetic Type 3) Conveyor belts Crushers - 6 (550 tons/hr)

6. Raw coal from bharat coal ltd. Dhanbad & bilaspur(MP) Wagon tippler To KSTPS from gudla via a single railway track hoppers bunkers Crusher house Coal mills (pulverization) Row coal feeders Boiler furnace ( tangential firing of pulverized coal)

10. RAW MATERIALUSED- Pulverized Coal

11. WORKING FLUID – D.M. Water

12. COMBUSTION MEDIUM – Air

15. Type– Reaction

16. TECHNICAL SPECIFICATION- Rated output -- 110 MW Rated speed – 3000 rpm Direction of rotation – clockwise Type -3 cylinder, impulse reaction Heat flow at rated output – 2152.5 kcal/kwh Quantity of oil - 1800 liters

17. TURBINE

19. Material –Carbon steel ,Cr-Mo alloy

20. Benefit – Increase efficiency of plantREHEATER Reheater are used to raise the temp of steam which has been expanded once in high pressure turbine. They used the heat absorbed from the flue gases.

21. AIR PRI-HEATER Function - To raise the temperature of air Benefit - Increases the efficiency of plant Type - plate, tubular, regenerative KSTPS - uses REGENERATIVE type

22. AIR PRE-HEATER

23. GENERATOR It converts mechanical power into electrical power. PRINCIPLE- Electromechanical energy conversion TECHNICAL SPECIFICATION- Apparent output – 137.5 MVA Active output - 110 MW Power factor – 0.85 lag Excitation voltage - 230 Volt Rated voltage – 11 KV Rated speed – 3000 rpm Phase connection – star-star

24. ECONOMISER Function-To extract some part of heat from flue gases & heat the feedwater Process- Counter flow of flue gases & water Benefits- Increases efficiency

25. CONDENSER To provide lowest economic heat rejection temperature for the steam. Thus saving on steam required per unit of electricity. To convert exhaust steam to water for reuse thus saving on feed water requirement.

26. COLLING TOWER It converts hot water from into cold water. Its purpose is to re use of the water. Its increase the efficiency of plant. It increase the per capital investment of plant. In K.S.T.P.S. only unit 6th and 7th has cooling tower.

28. ELECTROSTATIC PRECIPITATOR Used for the removal of suspended particles and fly ash from industrial flue gases PRINCIPLE- Produces an electrostatic field which attracts the ionized carbon particles and other such particulates which cause environmental pollution. 22
