ABSTRACT:
In a melting/gasifying furnace including a coke-filled layer, coal is gasified by oxygen blown through tuyeres into a hot reducing gas which is caused to ascend through the coke-filled layer so as to melt reduced iron supported on the top of the coke-filled layer. The resulting molten iron flows down through the coke-filled layer, and is collected in the lowermost region of the coke-filled layer and discharged therefrom, while the hot gas is recovered. The thus recovered gas is fed into a shaft reduction furnace to reduce iron ores, and the thus formed reduced iron is supplied into the melting/gasifying furnace. In addition to the coal, a variety of fuels mainly comprising carbon and hydrogen such as heavy oil, natural gas, etc. are used for gasification. The fuel is blown through the tuyeres and/or charged through middle openings disposed above the tuyeres.
