The natural draft cooling tower is the right choice for large power plants. It offers the following advantages :-
    1. power saving (no power consumption to induce air flow- no fan)
   2. environmentally friendly
   3. no mechanical noise (no fan)
   4. safety of operation
   5. no recirculation as the plume is rejected at high level
   6. limited plot area
   7. high longevity (generally more than plant life expectancy)
   8. Payback period between 8 and 16 years depending on several factors
