What Is the Combustion Equivalence Ratio, Excess Air & Flue O2 Calculator?
This tool computes combustion equivalence ratio, excess air & flue o2 calculator with high precision arithmetic.
How Does the Combustion Equivalence Ratio, Excess Air & Flue O2 Calculator Work?
Connects measured dry flue gas oxygen percentage (% O2) to excess air coefficient λ and fuel-to-air equivalence ratio Φ for industrial boilers and gas turbines.
Combustion Equivalence Ratio, Excess Air & Flue O2 Calculator Formula & Variables
The core mathematical equation utilized by this calculator is expressed as:
\Phi = \frac{(F/A)}{(F/A)_{\text{stoich}}} = \frac{1}{\lambda}, \quad \% O_{2,\text{dry}} \approx \frac{21 (\lambda - 1)}{\lambda - 1 + 0.21 + \text{ratio}}Connects measured dry flue gas oxygen percentage (% O2) to excess air coefficient λ and fuel-to-air equivalence ratio Φ for industrial boilers and gas turbines.
