The nitrogen oxides appear to leave the stratosphere by downward migration to the troposphere, or by absorbing ultraviolet light and breaking back down to nitrogen and oxygen. The latter mechanism occurs mostly in the upper stratosphere, the former in the lower stratosphere. The relative rates at which nitrogen oxides enter and leave the stratosphere by natural causes are not well known. The importance of the nitrogen oxide "sink" far ozone was not even realized until a few years ago.

  • Air Pollution
CONT

The alternatives for nitrogen oxide control are boiler operation changes, combustion equipment modifications to reduce NOx formation, and flue gas treatment ... In the U.S. and Canada, combustion modification (CM) is the most common method of NOx reduction. NOx can be reduced by injecting the combustion air in two stages, normally by reducing air flow to the burner and injecting the remainder through "overfire" air ports in the side of the boiler. Low-NOx burners that accomplish staged conditions within the burner flame have also been developed. Staged combustion ... reduces emission by 15-25%.

CONT

Les procédés de réduction du taux d'oxyde d'azote sont les suivants : modifications du fonctionnement de la chaudière, modifications de l'équipement de combustion visant à réduire la formation de NOx, et traitement des gaz de combustion pour l'extraire des gaz. [...] Modifications de la combustion : aux États-Unis et au Canada, c'est la méthode la plus courante de réduction du NOx. On peut obtenir cette réduction en injectant l'air de combustion en deux étapes, habituellement en réduisant le courant d'air arrivant au brûleur et en injectant le reste de l'air par des entrées d'air secondaire pratiquées sur le côté de la chaudière. On a également mis au point des brûleurs à faible émissions de NOx qui réalisent les conditions de combustion par étape à l'intérieur de la flamme du brûleur : [...] Les brûleurs à "faible taux d'émissions de NOx" sont efficaces et sont souvent utilisés au Japon en liaison avec type standard de combustion par étapes et le procédé de recirculation des gaz.

Testimony presented to the Sub-committee by representatives of the automobile industry disputed the need for reduced emissions of motor vehicle NOx. Their objections can be placed in three categories. First, the industry representatives argued that motor vehicle NOx emissions contribute little to acid rain and imposition of the one-gram standard will yield little beneficial effect.
