Abstract
Moyens pour empêcher la formation de bioxydes d'azote par brûlage de combustible. On utilise un four primaire et un four secondaire, placés en série et réglés pour recevoir chacun de 50 à 70 % de l'air stoechiométrique, le total d'air admis allant de 105 à 125 % de la quantité stoechiométrique. Application particulière : chambres de combustion de générateurs de vapeur.
