    Definition technique for lowering NOx emissions from a combustion where some of the combustion air is directed into the primary combustion zone while the balance is directed into secondary and even tertiary zones in some cases, making the primary zone fuel rich and hence less conducive to NOx formation Reference "Charles E.

    Comment "The unburned combustibles from the primary zone are then combusted in the secondary and tertiary zones. While the overall stoichiometry may be the same as in a conventional burner, the peak flame temperature is much lower in the staged air case because the combustion process is staged over some distance while heat is simultaneously being released from the flame. The lower temperatures in the staged air flame help to reduce the NOx emissions. Reference: Charles E. Baukal, Jr. Industrial Combustion Pollution and Control.

    Comment "The excess of O2 from the primary zone is then used to combust the fuel added in the secondary and tertiary zones. While the overall stoichiometry may be the same as in a conventional burner, the peak flame temperature is much lower in the staged fuel case because the combustion process is staged over some distance while heat is simultaneously being released from the flame. The lower temperatures in the staged fuel flame help to reduce the NOx emissions.Reference: Charles E. Baukal, Jr. Industrial Combustion Pollution and Control.
