ABSTRACT:
In addition to introducing steam and/or oxygen in the heated airblast through the tuyeres of a conventional blast furnace to provide a blast furnace gas enriched with carbon monoxide and hydrogen, air and/or steam can be forced through the molten pig iron which has been withdrawn from the blast furnace into a separate reactor having a modified construction similar to the basic oxygen furnace for the purpose of producing large volumes of hydrogen. The blast furnace gasses can be combined with the gasses from the reactor to provide a clean burning fuel for use in power plants and the like or the hydrogen from the reactor can be utilized directly in fuel-cell technology. The resulting iron oxides (magnetite, etc.) which result from the pig iron-steam reaction can then be recycled through the blast furnace.
