Ppt on thremal power station surtgarh by ashok khoja

  1. 1. By: Ashok khoja E.E. FINAL YEAR
  2. 2. SURATGARH THERMAL POWER PLANT
  3. 3. THERMAL POWER STATiON
  4. 4. •Coal handling plant•BOILER•Steam Turbine1.DEAERATOR2.4. Heat excHangers3.SUPER HEATER4.CONDENSOR5.FEED WATER HEATER
  5. 5. Coal handling plant
  6. 6. Boiler
  7. 7. THE BOILER SYSTEM COMPRISES OF Feed water system:-Feed water system provides water to the boilerSteam system:- steam system collects and controls the steam produced in the boilerFuel system:- The fuel system includes all equipment used to provide fuel. Two sources of feed waterCondensate or condensed steam returned from the processes. Makeup water (treated raw water) which must come fromoutside
  8. 8. Steam TurbineIt is a machine in which a shaft is rotated steadily by reaction of steam, air upon blades of a wheel.When Steam is used then called steam turbine. Kinetic Mechanical Energy power
  9. 9. turbine princple
  10. 10. 3. DeaeratorA deaerator is a device that is widely used for the removal of air and other dissolved gases from the feed water to steam generating boilers In particular, dissolved oxygen in boiler feedwaters will cause seriousIt also combines with any dissolved carbon dioxide to form carbonic acid.Most deaerators are designed to remove oxygen down to levels of 7 ppb by weight (0.0005 cm³/L) or less.
  11. 11. 4. Heat excHangersHeat exchangers are equipment that transfers heat from one medium to another.Heat exchanger performance can deteriorate with time, off design operations and other interferences such as fouling, scaling etc.It is necessary to assess periodically the heat exchanger performance in order to maintain them at a high efficiency level.
  12. 12. 5. Super HeaterA super heater is a device in a steam engine that heats the steam generated by the boiler again, increasing its thermal energy.Super heaters increase the efficiency of the steam engine, and were widely adopted.Super heaters were applied to steam locomotives to most steam vehicles, and to stationary steam engines including power stations.
  13. 13. 6. CondenSer
  14. 14. 8. Feed water HeaterThe feed water heating equipment then raises the temperature of the water by utilizing extraction steam from various stages of the turbine.Preheating the feed water reduces the irreversibilitys involved in steam generation
