CONT

L'influence de l'oxygène est importante, à cause de l'intérêt de plus en plus grand porté à l'application de l'enrichissement en oxygène aux fournaises industrielles qui fonctionnent au gaz naturel. L'avantage d'ajouter de l'oxygène à l'air ou au jet de combustible se traduit par une augmentation du flux de chaleur, tout en gardant constant le rapport air/combustible, ce qui produit des systèmes de combustion plus efficaces.
