Abstract

Dispositif permettant de limiter l'échappement de fumées de combustion vers l'extérieur d'un four continu de réchauffage de produits sidérurgiques et en particulier de brames, notamment d'un four tunnel, au niveau de l'ouverture située l'entrée du four. La première rangée de brûleurs est composée d'au moins deux brûleurs (2a,2c) placés une même distance (D) de l'entrée du four et proximité de l'entrée du four et les brûleurs de la première rangée de brûleurs sont inclinés principalement d'un angle A vers la sortie du four.
