CO₂ in flue gas – what it means and how it relates to combustion regulation

What is CO₂

Carbon dioxide is a natural product of the complete combustion of carbon and hydrocarbons.

What it helps us understand

In combination with O₂ and CO, it indicates whether the air-to-fuel ratio is in the correct range.

Attention

There is no single correct CO₂ value for all installations. The evaluation depends on the fuel, burner, and manufacturer.
