technical NOTES

(Project Pridr) #1
What are the ways to improve ACC Performance?


  • Optimization of air flow system (higher efficiency)

  • Installation of wind screens to counter negative effects of cross winds on ACC’s

  • Installation of fogging system (adiabatic cooling)

  • Elimination of hot air recirculation

  • Leak detection of vacuum system

  • Better and more efficient cleaning methods for finned tube bundles
    Advantage of Dry Cooling System
    System Wet Cooling System Dry Cooling System
    Major Equipment s Cooling Tower and surface
    condenser


Air Cooled Condenser

Availability of coolant Water at a cost or is it avail-
able?


Air Is free

Plant Location Should be near water and
fuel source


Water source is not
criteria
Maintenance cost High 25% of that for wet
cooling system
Effluent treatment Necessary Not Necessary


Fouling and Scaling Major concern Not a concern


Cleaning Frequent tube side cleaning
is necessary


Occasionally fin clean-
ing is required
Total Plat set up Involves intake water, pump-
ing system and storage
facility


No such infrastruc-
tures required

Space for complete system Same Same


Annual Energy consumption High Low
