More Information
Summary:In order to make it possible economically to gasify coal including carbon-containing gasification residues completely to give product gases which essentially consist of CO and H2 and are virtually sulphur-free and are suitable as high-grade reducing gas for downstream reduction processes, without expensive gas scrubbing and gas separation installations being necessary, it is proposed according to the invention to combine an oxidising high-temperature fluidised-bed gasifier (10) (pneumatic flow gasifier) and a molten iron bath gasifier (11), the gasification residue of the oxidising fluidised-bed gasifier being gasified without residue in the molten iron bath gasifier to give a virtually sulphur-free product gas essentially consisting of CO and H2, and it being possible to utilise the product gas of the oxidising fluidised-bed gasifier and the product gas of the molten iron bath gasifier separately or together as a high-grade reducing gas for carrying out reduction processes.
