Abstract

On chauffe séparément les deux corps solides à l'état de lits fluidisés 8 et 9 à une température voisine de la température de la réaction entre les deux corps ou inférieure à la température maximale qu'ils peuvent supporter sans décomposition néfaste. On réunit ensuite les deux corps solides ainsi chauffés pour constituer un lit fluidisé unique 28 et on maintient ce lit fluidisé à une température moyenne inférieure à celle de la réaction entre les deux corps, en portant localemen lesdits corps à une température au moins egale à la température de réaction entre les deux corps. Application notamment à la fabrication du clinker pour ciment et du silicate de soude.
