Abstract
A method of producing a sintered ore includes charging a sintering raw material containing a powder ore and a carbonaceous material onto a circulatory moving pallet to form a charged layer, igniting the carbonaceous material on a surface of the charged layer, introducing air above the charged layer containing a gaseous fuel diluted to not more than a lower limit of combustion concentration with wind boxes arranged below the pallet into the charged layer by suction, and combusting the gaseous fuel and the carbonaceous material in the charged layer, wherein more than 50% of a total supply of the gaseous fuel is supplied in a front ½ portion of a region supplying the gaseous fuel.
