Theoretical (dry) CO₂ concentration in flue gas as a function of excess air - useful cross-check against stack analyser.
Formula
$$ CO_2\% = \frac{CO_2\text{,max}}{\lambda} $$Symbol legend
| Symbol | Meaning | Unit | Source |
|---|---|---|---|
| $CO_{2,\text{max}}$ | Stoichiometric CO₂ max | % v/v | fuel property |
| $λ$ | Excess air factor | - | combustion analyser |
| $CO_2\%$ | Actual flue CO₂ | % v/v | result |
