Air Cooled Condensers
Reject turbine or process exhaust heat to ambient air — preferred where cooling water is scarce or costly.
What is an air cooled condenser?
Air cooled condensers (ACC) condense exhaust steam by transferring heat to ambient air through finned tube bundles and forced-draft fans. They avoid large cooling-water circuits — useful for inland power and process plants with limited water.
Grandeh supports ACC block programmes with related steam and boiler equipment fabricated at Aurangabad — scoped to the steam-side and plant interfaces of each project.
How an ACC works
- Steam side — turbine or process exhaust steam enters the ACC tube bundles
- Air side — fans drive ambient air across the fins; steam condenses inside the tubes
- Condensate — returns to the feedwater / condensate system for reuse
Typical system elements
| Element | Role |
|---|---|
| Finned tube bundles | Primary steam-to-air condensing surface |
| Steam ducting & headers | Distribute exhaust steam into the tube banks |
| Fans & drive gear | Move cooling air across the fins |
| Support structure | Carries bundles, fans and walkways |
| Condensate collection | Returns condensate to plant systems |
| Dampers / isolation | Isolation and bypass where the gas / steam path requires it |
What information helps scope ACC-related equipment?
Steam-side data
- Exhaust steam flow and pressure (or turbine heat balance extract)
- Design / operating condenser pressure target
- Condensate temperature and return routing preferences
Site and ambient data
- Design dry-bulb ambient temperature
- Altitude and site wind / dust conditions
- Plot plan, structural interface and lift constraints
Related Grandeh scope (when required)
- Boiler or pressure-part packages attached to the ACC block
- Ducting, dampers and fabricated steel interfaces
- IBR / TPI documentation expectations
Where ACC fits
- Power and captive power plants with limited cooling water
- Process plants that reject steam to air instead of a cooling tower
- Projects pairing ACC blocks with industrial boilers or steam auxiliaries
See a recent boiler dispatch for an ACC block unit.
