Abstract

A blast furnace for use in an apparatus such as a steel making apparatus or a gasifier includes a crucible (35) having a tap hole (61) for discharging molten slag therefrom. The furnace includes a lance (30) for introducing fuel and oxygen into the crucible (35) and instrumentation (68) for continuously measuring characteristics of the molten slag discharged through the tap hole to control processing of fuel and oxygen in the crucible (35).
