Abstract:
A process for sintering incineration residues from an incineration plant, said process comprising:introducing incineration material into an incineration zone comprising an incineration bed on a furnace grate; introducing primary incineration air to said incineration zone from below said furnace grate; firing said incineration material in said incineration bed to effect incineration of said material to produce incineration residues and fly ash; controlling said incineration to sinter said incineration residues to form slag in an upper region of said incineration bed in said incineration zone; separating unsintered incineration materials from said slag when said incineration residues leave said incineration zone; and feeding said unsintered residues back to said incineration zone.
