CO in a natural gas burner: what it indicates and why it increases

CO is one of the most important measurements during combustion adjustment. Its increase indicates that the fuel is not fully oxidized.

Insufficient air

One of the main causes of high CO is an incorrect air-gas ratio.

Poor mixing

A dirty burner head, incorrect diffuser position, or problems with the mixing system can cause a locally rich mixture.

Draft problem

Inappropriate conditions in the combustion chamber or the chimney can affect the flame and emissions.

Correct approach

We do not just change air or gas at random. We systematically check pressure, burner head, air, draft, and flue gases.
