    • In a double-incline shaft kiln in which ore materials are charged into the furnace from the top of a vertical external portion of the shaft and are calcined by burners installed in the lower portion of the shaft, the calcining zone is effectively extended by the provision of an injector which causes the hot gas to flow in the lower portion of the shaft parallel to the flow of ore materials. Further, at the turnover locations for the ore descending through the shaft, the width of the shaft is broken into at least two portions which promotes a more even velocity of the material flow across the width of the shaft so as to enable combustion control and the prevention of the ash of solid fuel, such as coal, from mixing with the calcined material to cause discoloration and lumps.
    • 在双斜轴窑中,矿石材料从轴的垂直外部部分的顶部装入炉中并且通过安装在轴的下部的燃烧器进行煅烧,煅烧区通过提供有效地延伸 的喷射器,其使热气体平行于矿石材料的流动在轴的下部流动。 此外,在通过轴下降的矿石的周转位置,轴的宽度被分解成至少两个部分,其促进材料流通过轴的宽度的更均匀的速度,以便能够进行燃烧控制和 防止诸如煤的固体燃料的灰与煅烧的材料混合以引起变色和团块。

    • Disclosed is a pulverizing, drying and transporting system for a pulverized fuel of a blast furnace of the type having at least one hot stove for supplying hot blast air, said hot stove also providing hot stove exhaust gas. The system includes a pulverizing and drying unit for pulverizing lamp raw fuel and drying the pulverized fuel. The hot stove gas is supplied to the pulverizing and drying unit. The hot stove exhaust gas dries the pulverized fuel and conveys it to a pulverized fuel collecting and separating device which separates the gas from the pulverized fuel. The line supplying the hot stove gas to the pulverizing and drying unit includes a heating device for selectively supplying additional heat to the hot stove exhaust gas. Moreover, the line for supplying the hot stove gas to the pulverizing and drying unit can include at least one of a temperature stabilizing device and a cooling device. The heating and cooling devices and controlled by a controller sensitive to the gas temperature at the outlet of the pulverizing and drying unit for maintaining the gas temperature at the outlet of the pulverizing and drying unit at a constant level. The temperature stabilizing device maintains the gas temperature at the outlet of the temperature stabilizing device at a designated level.
