Abstract:
Apparatus for generating a reducing gas in a molten iron bath gasifier while simultaneously producing direct reduced iron oxide in an associated shaft furnace with the gas from the gasifier. The apparatus includes means for controlling the temperature of the reducing gas to the shaft furnace, means for cleaning, upgrading, and introducing spent top gas from the direct reduction furnace to the molten bath gasifier as a gaseous coolant to cool the reaction with the bath and reduce refractory wear within the gasifier.
