Abstract

L'invention se rapporte aux lits fluidisés. Elle se caractérise en ce qu'un conduit 16 amène sous le fond poreux il un mélange gaz/air non-stoéchiométrique tandis qu'un autre conduit 1 disposé dans les particules réfractaires 14 fournit de l'air ou du gaz qui se mele à ce mélange pour former un mélange stoéchiométrique à l'intérieur de la masse des particules réfractaires. Application : traitements thermiques.
