ABSTRACT:
A melter gasifier (10) for the production of a metal melt and of a reducing gas is provided with feed ducts (17, 16, 9) for oxygen-containing gases, carbon carriers and the metal carriers. From the melter gasifier (10) there departs at least one gas discharge duct (12) for reducing gas generated in the melter gasifier (10). Also, a tap (18) for the metal melt and for slag is provided. To be able to process fine-particulate metal carriers without the need of briquetting and without entrainment of the supplied fine-particulate metal carriers out of the melter gasifier (10) by the reducing gas generated therein, at least one feed duct (9) feeding the metal carriers is arranged in the region of a dome (30) terminating the melter gasifier (10) toward the top, and in the interior of the melter gasifier (10) below the entry site of the feed duct (9) for the metal carriers a refractory slanting wall (33) inclined towards the vertical line, on which there impinge the metal carriers sinking downward due to gravitational forces. Further, above the slanting wall (33) a heating means (38) is provided by which the area between the entry site of the feed duct (9) for the metal carriers and the slanting wall (33) may be heated.
