- Definition technique for lowering NOx emissions from a combustion where some of the fuel 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 "COM-Terminology Coordination, based on:Charles E.

- 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.

- Definition méthode permettant, par la création d'une première zone de combustion à fort excès d'air, donc à basse température, suivie d'une zone secondaire riche en combustible où les radicaux hydrocarbonés réduisent le NO formé en N2, de réduire la production des oxydes d'azote qui se forment dans les chambres de combustion par la réaction entre l'azote et l'oxygène de l'air Reference "COM-FR sur la base du site d'Energie plus > energie-plus-magazine > reduction-des-nox-traitement-primaire-adapter-la-combustion, http://atee.fr/energie-plus-magazine/reduction-des-nox-traitement-primaire-adapter-la-combustion [11.9.2015]"
