摘要： Apparatus for supplying diluted gaseous fuel to not more than a lower limit combustion concentration at downstream of suction type sintering machine including a hood having similar width as a circularly-moving pallet and arranged above charged layer to surround the pallet in all directions, pipes disposed at upper position of charged layer in the hood and supplying the fuel air inside the hood, baffle plates formed by arranging plate materials having dog-leg shaped cross-section in plural rows and steps at intervals in the widthwise and height directions, respectively, of the hood to make each interval formed between adjacent plate materials in widthwise direction of the hood in each steps vertically alternate; fences having a void and arranged on both sides upper ends of the hood; vortex suppressing plates formed between fences at intervals having a void ratio, 20˜80%; whereby the gaseous fuel leakage supplied to the outside is prevented.

摘要： 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.

摘要： 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.
