    • PURPOSE:To accelerate atomization of an auxiliary gasification agent and to ensure exact approuch to a high-temp. combustion site formed by an oxygen jet, by using a non-immersed, multi-hole lance in which an auxiliary gasification agent nozzle is combined with an oxygen nozzle in the outlet portion thereof. CONSTITUTION:A non-immersed, multi-hole lance 3 is formed by arranging outer holes a2 and a3 outside a central hole a1 and combining the multi holes a2 with the multi holes a3 in the outlet portion. Then coal 5 is introduced into the central hole 5, an auxiliary gasification agent 7 such as steam or CO2 is blown into the multi holes a2 and oxygen 6 is blown into the multi holes a3. The gasification agent 7 is combined with the oxygen 6 in the outlet portion of the multi-holes a3 to be blown into the corresponding amt. of molten iron 2 in a smelting tank 1 for gasification.
    • 目的:加速辅助气化剂的雾化,确保高温下的精确应用。 通过使用非浸入式多孔喷枪形成的燃烧部位,其中辅助气化剂喷嘴在其出口部分与氧气喷嘴组合。 构成:通过将外孔a2和a3设置在中心孔a1的外侧并将多孔a2与出口部中的多孔a3组合而形成非浸没式多孔喷枪3。 然后将煤5引入中心孔5中,将诸如蒸汽或CO 2的辅助气化剂7吹入多孔a2中,将氧气6吹入多孔a3。 气化剂7与多孔a3的出口部分中的氧6结合,成为相应的。 在用于气化的冶炼罐1中的铁水2。

    • PURPOSE:To improve gasifying efficiency, by installing a slag notch, in the center of the bottom of a molten iron bath-gasifying furnace and electromagnets on the outer surface of the furnace and by centrifuging iron bath from slag by electromagnetic induction agitation of molten iron bath to discharge continuously the slag through the slag notch. CONSTITUTION:Into a molten iron bath furnace 11 covered with steel mantle 13 comprising a nonmagnetic iron plate, pulverized coal and O2 are blown through a lance 3 and steam is blown through a lance 4 to reach the surface of molten iron bath 6 and thus the coal is gasified. If magnets 14 are energized and the molten iron bath 6 is rotated by electromagnetic induction agitation, slag 7 on the bath surface is rotated at an angular speed smaller than that of iron bath 6, the iron bath moving toward a wall surface side in the furnace. On the other hand, the slag 7 gathers in the center of the furnace to be discharged continuously through a central slag, notch 12, and the amount of discharge is controlled by the angular speed of rotary magnetic field. Gas evolving in the furnace if sent through a hood 5 to a gas holder.
    • 目的:为了提高气化效率,通过在铁水浴气化炉底部的中心和炉外表面的电磁铁上安装炉渣,并通过铁水的电磁感应搅拌离心铁渣 通过炉渣切槽连续排出炉渣。 构成:在由包含非磁性铁板的钢罩13覆盖的铁水浴炉11中,通过喷枪3吹入粉煤和O 2,并且通过喷枪4吹入蒸汽到达铁水浴6的表面, 煤气化。 如果磁体14通电并且通过电磁感应搅拌使铁水浴6旋转,则熔池表面上的炉渣7以比铁浴槽6小的角速度旋转,铁浴朝着炉子的壁表面侧移动 。 另一方面,炉渣7集中在炉中心,通过中心炉渣,缺口12连续排出,排出量由旋转磁场的角速度控制。 如果通过发动机罩5发送到气体支架,气体在炉中演变。
