摘要：

Thermodynamic analysis of the reduction of iron and the material balances of carbon shows that the CO2 levels in the blast-furnace gas may be maintained by lowering the carbon consumption in the direct reduction of iron from its oxides. To this end, natural gas and blast-furnace gas are injected into the furnace or else some of the oxidized sinter and pellets may be replaced by reduced pellets. © 2013 Allerton Press, Inc.
