Method for the direct reduction of iron and production of fuel gas using gas from coal |
摘要 |
A method for the direct reduction of iron and production of fuel gas in which a fossil fuel is gasified to produce a hot gas which is tempered with a carbon dioxide rich gas. The mixture is reacted with carbon to upgrade it in reducing potential and is desulfurized by reaction with lime in a first shaft furnace to form a hot reducing gas. The hot reducing gas is utilized as the reductant in a counterflow shaft reduction furnace, a minor portion of the spent reducing gas is recycled as tempering gas for the gas from the hot gasifier, and the major portion of spent reducing gas becomes a source of fuel gas.
