Cooling Towers

  1. 1. Cooling Towers Presented by; Satender Kumar Rahul Bajpai Mohit Gupta
  2. 2. What is the necessity of cooling condenser water ?
  3. 3. Cooling systems Open or once Through systems Closed systems Mixed Systems Water cooling air cooling Cooling ponds Cooling towers Direct dry type Cooling towers Indirect dry type Cooling towers
  4. 4. Mixed cooling systems
  5. 5. Induced draft <ul><li>Counter flow </li></ul><ul><li>Cross flow </li></ul>Mechanical draft cooling towers 2 )
  6. 6. Counter flow induced draft cooling towers
  7. 7. Cross flow induced draft cooling towers Proceed
  8. 8. HOME
  9. 9. Mechanical Draft cooling towers Forced draft 1 ) back
  10. 10. Types of cooling towers:- <ul><li>1) Natural draft </li></ul><ul><li>2)Mechanical draft </li></ul>
  11. 11. Natural draft cooling tower
  12. 12. HOME
  13. 13. A disadvantage of using wet or evaporative cooling towers!
  14. 14. Water evaporation rate = 0.6 gallon per KWhr(approx) = 9700 acre ft per year for a 800 MW plant (equivalent to one full river)
  15. 15. Dry cooling towers or air cooling towers <ul><li>Two types of dry cooling systems:- </li></ul><ul><li>1) Indirect or hellar dry cooling systems </li></ul><ul><li>2) Direct dry cooling systems </li></ul>
  16. 16. Direct dry type cooling system proceed
  17. 17. Indirect or hellar dry type cooling system
  18. 18. Dry cooling towers + wet cooling towers = Dry wet combined cooling towers
  19. 19. Dry wet combined cooling towers proceed
  20. 20. Environmental effects of cooling towers!
  21. 21. Some major effects of drift droplets:- <ul><li>Icing or horizontal or vertical surfaces can occur from drift which can cause troubles on highways. </li></ul><ul><li>Deposition of drift in the vicinity if cooling tower makes it a potential environmental concern. </li></ul><ul><li>It effects vegetation, soil, ground water, and acts a a corrosive agent. </li></ul><ul><li>Damage to concrete structure due to chloride compounds producing potholes. </li></ul>
  22. 22. Thank you ? QUESTIONS
