If fuel is increased above this point, the additional fuel will not react and will pass unchanged to the flue gas - so above stoichiometric the CO2 % will start to fall off. Ideally, there will be no O2 in flue gas below stoichiometric, and the O2 ratio will increase as air flow is increased above stoichiometric.
