METHOD AND DEVICE FOR MANUFACTURING LOW SULFUR CONTENT REDUCING GAS

摘要

A reducing gas is generated in a molten metal bath wherein fuel, oxygen and a flux are injected into a pressure-tight vessel beneath the bath to produce a partially-desulfurized partial-oxidation gas having a hydrogen and carbon monoxide content of at least 50% and the process is controlled by injecting steam or a fuel rich gas consisting substantially of hydrogen, carbon monoxide methane, or a mixture thereof as a coolant to the metal bath between 1350 DEG C and 1600 DEG C by adjusting the coolant flow rate.
