Abstract

Four de calcination par micro-ondes et à lit fluidisé L’invention concerne un four de calcination par micro-ondes et à lit fluidisé comprenant une enceinte de chauffe (4) comprenant, en partie haute, une arrivée (8) de produits (P) à traiter et une sortie (10) pour évacuer les produits traités, et, en partie basse, une grille de diffusion (12) apte à supporter les produits admis dans l’enceinte, au moins un guide d’ondes (14) débouchant à l’intérieur de l’enceinte de chauffe et raccordé à un générateur de micro-ondes (18), un conduit d’admission d’air ou de gaz chauds (20) débouchant dans la partie basse de l’enceinte de chauffe et raccordé à un générateur de gaz chauds (22), des moyens (24) pour diffuser l’air ou les gaz chauds admis dans la partie basse de l’enceinte de chauffe en direction des produits à traiter afin de générer un lit fluidisé, un conduit de récupération de gaz chauds (26) s’ouvrant vers l’extérieur, et un conduit de vidange (19). Figure pour l’abrégé : Fig. 1.
