Claim:
1. A method for producing a sintered ore, the method comprising: charging a sintering raw material including powder ore and carbon material onto a circularly moving pallet to form a charged layer; igniting the carbon material on a surface of the charged layer; supplying a gaseous fuel from a plurality of gaseous fuel supplying devices installed downstream of an ignition furnace in a machine length direction, a total amount of supply of the gaseous fuel supplied from the gaseous fuel supplying devices being set to be constant; sucking air above the charged layer using a wind box disposed below the pallet and introducing the air into the charged layer, the air including the gaseous fuel; increasing or decreasing an amount of supply of the gaseous fuel supplied from each gaseous fuel supplying device depending on an amount of air sucked into the charged layer in a region in which each gaseous fuel supplying device is installed; and combusting the gaseous fuel and the carbon material within the charged layer to produce the sintered ore.
