CA 2401253

The invention relates to a method of regulating a roasting furnace in fluidized bed roasting. Part of the roasting furnace grate is separated off into a separate grate section, known as the overflow grate, where the nozzles and the amount of roasting gas blown through them can be regulated independently of the main grate. It is advantageous to position the separately regulated grate in the section of the furnace where the overflow aperture is located.

L'invention concerne un procédé permettant de réguler un four de grillage dans le cadre d'un grillage sur lit fluidisé. Pour ce faire, on sépare une partie de la grille du four de grillage en une section grille à part, appelée grille de débordement, où les buses et la quantité de gaz de grillage soufflés dans lesdites buses peuvent être régulées indépendamment de la grille principale. Il est avantageux de positionner ladite grille que l'on peut réguler de façon séparée dans la partie du four où se trouve l'ouverture de débordement.
