Abstract

L'invention concerne le nettoyage de pièces dans un lit fluidisé. Elle se rapporte à un procédé dans lequel un gaz de fluidisation transmis à une chambre 10a fluidise un lit 16 de particules afin que les revêtements portés par les pièces P soient pyrolisés. Les produits inflammables qui se dégagent dans l'espace 21 ne peuvent pas s'enflammer car un fluide protecteur est transmis par une buse 54 et dilue les gaz formés. Application à la récupération des pièces usées et défectueuses.
