METHOD AND APPARATUS FOR REDUCING IRON OXIDE TO MOLTEN IRON USING OXY-FUEL BURNERS |
摘要 |
<p>A method and apparatus for reducing particulate iron oxide to molten iron utilizing solid carbonaceous fuel as reductant in a shaft type reducing furnace, in which a furnace burden is formed of a mixture of iron oxide lumps or pellets and particulate solid fuel. Reacted top gas is upgraded and recirculated through the burden in counterflow relationship thereby heating and reducing the burden. The heat for reduction is generated by passing electric current through the burden. A portion of the heat for melting of reduced iron and a supplemental source of hot reducing gas is provided by oxy-fuel burners located in the shaft furnace above the molten iron pool.</p> |
