Abstract (en)
[origin: EP2322675A1] A method for producing sintered ore includes a charging step of charging a sintering raw material containing ore fines and a carbonaceous material onto a circulating pallet to form a sintering bed of the sintering raw material on the pallet; an ignition step of igniting the carbonaceous material on a surface of the sintering bed using an ignition furnace; a diluted gaseous fuel producing step of producing a diluted gaseous fuel in a concentration of a lower flammable limit concentration or less by supplying a gaseous fuel to air above the sintering bed so as to dilute the gaseous fuel; and a combustion step of combusting the diluted gaseous fuel in the sintering bed by sucking the diluted gaseous fuel and air into the sintering bed by suction through a wind box disposed below the pallet while combusting the carbonaceous material in the sintering bed with the air sucked into the sintering bed, thus forming a sinter cake.
