๐ Calculation Methodology & ACC Power Plant Standards
Direct Dry Cooling A-Frame Configuration
Exhaust steam from the steam turbine flows through large overhead steam distribution ducts into inclined finned tube bundles arranged in a 60ยฐ A-frame to minimize footprint and fan power.
Initial Temperature Difference (ITD)
ITD is the primary design metric in dry cooling: $ITD = T_{sat}(P_{back}) - T_{amb}$. Lower ITD values achieve deeper vacuum but require larger heat transfer areas.
Key Engineering Assumptions
- Single-row or two-row flat steel/aluminum finned tube bundles.
- Forced draft axial fans with typical static efficiency $\eta = 65\%$.
- Zero water consumption, suitable for arid regions and water-constrained power plants.
