Direct Air Cooled Condenser (ACC)
It is a cooling system in which the exhaust steam of steam turbine is directly condensed into water through the tube bundle of air cooled condenser using air as cooling medium. Its heat exchange system mainly includes: air cooled condenser, air supply system, support structure, exhaust duct system, condensate collection system, vacuum-pumping system, cleaning system, electrical system and instrument control system.
Main Components of Direct Air Cooled Condenser System
1. Air Cooled Condenser
2. Air Supply System
3. Exhaust Duct System
4. Condensate Collection System
5. Vacuum-pumping System
6. Cleaning System
7. Electrical System
8. Instrumentation and Control System
9. Support Structure
-
01
The discharged steam condenses in the exhaust duct, and the latent heat is discharged by a large amount of air driven by the fan.
-
02
No water consumption (except for cleaning exhaust duct bundle).
-
03
It works well in regions with low average temperature.
-
04
Compared with water cooling, air can be obtained free of charge, air corrosivity is low, and the operation and maintenance cost of air cooling is relatively low.
