What it is: CO is the result of incomplete combustion. The goal of burner/boiler design is to achieve complete combustion in order to release all of the energy available in the fuel. If some carbon molecules cannot find some oxygen molecules, they will partially convert to CO (carbon monoxide) rather than CO2 (carbon dioxide).
