Abstract
Method for producing sintered ore in which air above a charged layer containing a gaseous fuel supplied from a plurality of gaseous fuel supplying devices installed in a machine length direction on a downstream of an ignition furnace of a sintering machine is sucked by a wind box disposed below a pallet and is introduced into the charged layer, and the gaseous fuel and the carbon material are combusted inside the charged layer to produce the sintered ore, wherein a total amount of supply of the gaseous fuel supplied from the gaseous fuel supplying devices is set to be constant, the amount of supply of the gaseous fuel supplied from each gaseous fuel supplying devices is increased or decreased depending on an amount of air sucked into the charged layer in a region which each gaseous fuel supplying device is installed, thereby optimizing a supply ratio of the gaseous fuel.
