Theoretical Air and Excess Air Calculator
Calculate theoretical air requirement, excess air and flue gas oxygen.
1. Theoretical Air Requirement
Enter fuel analysis values and click calculate.
2. Excess Air Calculation
Enter Oâ‚‚ in flue gas and click calculate.
3. Calculate Oâ‚‚ in Flue Gas from Excess Air
Enter excess air percentage and click calculate.
Calculation Notes:
- Theoretical air is calculated from the fuel composition.
- Excess air is calculated from the measured Oâ‚‚ percentage in flue gas.
- Flue gas Oâ‚‚ can also be calculated from the excess air percentage.
