<p>An oxygen-gas fuel supply device for a sintering machine for: drawing in and introducing to a loading layer, using a window box installed below the palette, air obtained by injecting and enriching oxygen into an atmosphere in a hood provided above a raw material loading layer downstream of an ignition furnace, and supplying a gas fuel diluted to or below a combustion lower limit concentration; and burning the gas fuel and a carbonaceous material in the loading layer and manufacturing a sintered ore. Baffle plates are disposed in the hood at the intermediate portion in the height direction of the hood, the baffle plates being disposed as a plurality of rows of mountain-shaped plate material so that gaps are present in the horizontal direction and as a plurality of layers in the vertical direction so that the gap sections are arranged in a staggered manner. Gas fuel supply pipes for supplying the gas fuel into the air are disposed below the baffle plates. Oxygen supply pipes, in which at least the portion disposed in the hood is made of a copper alloy and/or a Ni alloy, are disposed above the baffle plates.</p> |
