Abstract

L'invention concerne une installation (01) de traitement thermique, en particulier de pyrolyse, de gazéification et/ou de combustion, de déchets circulant en continu, comportant une chambre de réaction (10) primaire allongée orientée horizontalement et dotée d'un lit de réaction (20) et d'au moins un élément d'entraînement en rotation (30), la chambre de réaction (10) primaire comprenant, sur une paroi (11), une ouverture d'alimentation (16) pouvant être fermée pour une alimentation en déchets et, sur la paroi (11), une ouverture de sortie (17) pouvant être fermée pour une sortie des résidus de réaction, le lit de réaction (20) étant fermé sur toute sa surface et exempts d'ouvertures, le lit de réaction (20) atteignant un point supérieur (21) et un point inférieur (22), la surface entre ceux-ci étant inclinée et/ou étagée, l'élément d'entraînement en rotation (30) étant orienté transversalement à l'axe longitudinal de la chambre de réaction (10) primaire et monté de manière rotative, et le cercle de rotation de l'élément d'entraînement en rotation (30) étant espacé de la surface du lit de réaction (20), la paroi (11) de la chambre de réaction (10) primaire pouvant être chauffée complètement ou partiellement.
