Abstract

A reactor for gasifying and/or melting feed materials, the reactor including a charging section with a feed opening, through which the feed materials are charged to the reactor from above and a pyrolysis section which has an expanded cross section and is located below the charging section so that a discharge cone of the feed material can form. Gas supply devices, open into the pyrolysis section substantially at a level of the expanded cross section and through which hot gases can be fed to the discharge cone. A melting and superheating section is located below the pyrolysis section and has a narrowing cross section. Upper injection devices are arranged so that an energy-rich medium is supplyable to the melting and superheating section immediately below a level of the narrowing section. A reduction section is located below the melting and superheating section. The reduction section has gas exhaust devices through which excess gases are exhausted. A hearth is provided with a tap below the reduction section for accumulating and draining molten metal and molten slag. Lower injection devices are provided through which an energy-rich medium is supplyable directly above the molten metal and slag and below the gas exhaust devices so as to prevent solidification of the molten metal and slag.
