Abstract

A blast furnace for use in an apparatus such as a steel making apparatus or a gasifier includes a vessel including a crucible. The furnace includes a lance for introducing fuel and oxygen into the crucible and instrumentation for determining density characteristics of molten material inside the crucible. In one embodiment, the blast furnace is able to adjust the input of fuel and/or oxygen into the crucible based on the measure density characteristics of the molten material. The blast furnace can also include structure for cooling and clinkering molten material discharged from the crucible.
