Abstract

L'invention concerne un procédé de traitement thermique et de valorisation de déchets de différents types, consistances et compositions, tels que du bois usagé chargé en polluants, de vieux pneus, des déchets industriels, des ordures ménagères et des déchets encombrants. L'invention concerne également un gazéificateur à fusion en cuve approprié pour mettre ledit procédé en oeuvre. Les déchets sont introduits directement dans la zone haute température H, après allumage dans le gazéificateur à fusion en cuve. Les constituants organiques contenus dans les déchets réagissent là avec l'oxygène. Les produits de réaction sont aspirés dans le creuset avec les déchets résiduels en flux continu. Les constituants organiques des déchets non consumés intégralement sont soumis à une désintégration pyrolytique. Il en résulte du coke de pyrolyse qui est consumé avec de l'oxygène dans la zone de réduction/fragmentation Z et le gaz brut est aspiré entre les zones 11 et 7.
