Abstract

La présente invention décrit un procédé pour améliorer l'arrivée d'énergie au cours du chauffage et de la fusion d'une masse de déchets, dans lequel un canal est brûlé dans la masse de déchets et de l'énergie supplémentaire pour le chauffage et la fusion de la masse de déchets est amenée à travers ce canal. Ledit procédé se caractérise en ce que ledit canal est brûlé dans la masse de déchets grâce à un jet de gaz chaud contenant de l'oxygène.
