    • 8. 2. COAL HANDLING PLANT • This plant have 3 parts... A. Wagon unloading system. B. Conveying belt system. C. Crushing system.
    • 9. IMAGE OF COAL HANDLING PLANT
    • 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. 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. 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. B. Crushing system
    • 14. 5. BOILER with FURNANCE
    • 15. four part is connected with the boiler & furnance section 1. Water treatment plant. 2. Ash handling plant. 3. ESP(Chimeny) 4. Turbine section.

    • 23. 6.TURBINE
    • 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. Working of turbine & generator:- STEAM TURBINE MECHANICAL ENERGY GENERATOR ELECTRICAL ENERGY
    • 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.
