CO Emission Calculator

A Signal of Incomplete Combustion

CO forms when fuel doesn't fully oxidize to CO2, most often from insufficient air, poor mixing, or a flame quenched too quickly. A well-tuned burner produces very little; rising CO is often the first sign something needs adjustment.

The Formula

CO Mass = Heat Input(GJ) × CO Emission Factor(g/GJ)

Worked Example

A well-tuned burner with 500 GJ heat input at the default 15 g/GJ factor:

CO = 500 × 15 = 7,500 g = 7.5 kg

How to Use This Calculator

Enter the total Heat Input in GJ.
Optionally adjust the CO Emission Factor (defaults to 15 g/GJ for a well-tuned burner).
Select Calculate to get CO mass emitted.
