Abstract

Four pour la fusion des métaux chauffé par combustible liquide ou gazeux. Le foyer comporte un brûleur dont l'air de combustion est préchauffé par passage dans une chambre à air comprise entre les parois intérieure et extérieure de la chemise du foyer et par passage dans un échangeur dans lequel circulent les produits de combustion. La chemise est isolée par une garniture réfractaire et une couche de matériau isolant. Le brûleur est formé de deux tubes concentriques entre lesquels passe de l'air de refroidissement Applications aux fours chauffés par combustibles liquides ou gazeux.
