    8. 8. 2. COAL HANDLING PLANT • This plant have 3 parts... A. Wagon unloading system. B. Conveying belt system. C. Crushing system.
    9. 9. IMAGE OF COAL HANDLING PLANT
    10. 10. COAL LOADED BY TRAIN • SOURCE OF COAL : COAL INDIA LTD. BCCL,SECL & ECL • MEANS OF TRANSPORTATION: - RAILWAY WAGONS • TYPE OF COAL : BITUMINOUS  TAKEN TO COAL MILLS THROUGH CONVEYOR BELTS.  CRUSHED INTO POWDERED FORM IN COAL MILLS.  WITH THE HELP OF PRIMARY AIR FANS IT IS TAKEN TO BOILER. • COAL HANDLING PLANTCOAL HANDLING PLANT
    11. 11. A. Wagon unloading system • Unload the coal from wagon to hopper. • Hopper allows to pass coal pieces ≤ 200mm • From hopper coal fall on vibrator which is supported by roller.
    12. 12. C.Conveying system • Belt are used to convey coal from coal handling plant to furnance. • Specification:- – Belt width : 1400mm – Speed : 2.2m/sec – Total install power : 360kw – Capacity : 1350/750 ton/hr – No. of conveyor: 38
    13. 13. B. Crushing system
    14. 14. 5. BOILER with FURNANCE
    15. 15. four part is connected with the boiler & furnance section 1. Water treatment plant. 2. Ash handling plant. 3. ESP(Chimeny) 4. Turbine section.
    16. 16. • SOURCE OF WATER :- CHAMBAL RIVER W.T.P. DIVIDED IN TWO PARTS :-  FILTERATION WATER PLANT  DEMINERALISED WATER PLANT
    17. 17. CHART OF W.T.P

    19. 19. ASH HANDLING PLANT ASH HANDLING PLANT
    20. 20. ASH HANDLING PLANT This plant can be divided into three sub plants as follows :- 1)Fuel and Ash Plant:- 2)Air and Gas Plant:- 3) Ash Disposal and & Dust Collection Plant:-
    21. 21. 4. ELECTROSTATIC PRECIPITATOR
    22. 22. WORKING OF PRECIPITATOR
    23. 23. 6.TURBINE
    24. 24. Designed for continuous operation at the rated output. Directly coupled with steam turbine, rotated at high speed of 3000 RPM. Two major parts:- (i) Stator (ii) Rotor Major parts of stator are (i) Stator frame. (ii)Stator core. (iii)Stator bars. (iv)Stator windings.
    25. 25. Working of turbine & generator:- STEAM TURBINE MECHANICAL ENERGY GENERATOR ELECTRICAL ENERGY
    26. 26. 8.Cooling System • In KSTPS hydrogen cooling system is employed for generator cooling. • Hydrogen is used because of its superior cooling properties & low density. • Thermal conductivity of H2 7.3 times of air. • Seal oil system are used in turbine for less friction in bearing. • Water cooling also used for any kind of fire.
    27. 27. 10. Transformer
    28. 28. Various Transformers In KSTPS – Generating Transformer – Unit Auxiliary Transformer (U.A.T.) – Station Transformer (S.T.) – Exciting Transformer – Earthing Transformer – Instrument Transformer
    29. 29. Generating Transformer
    30. 30. Specification of U.A.T.
