Abstract:
A melter gasifier (10) for the production of a metal melt which is at least partially reduced and contains a portion of fines, and of a reducing gas by gasification of coal, with feed ducts (17, 16, 9) for oxygen-containing gases, carbon carriers and the metal carriers running into said melter gasifier (10), which feed ducts (17) for oxygen-containing gases are arranged in the lower region of the melter gasifier (10), wherein at least one gas discharge duct (12) for reducing gas generated in the melter gasifier (10) departs from the melter gasifier and the melter gasifier (10) is provided with a tap (18) for the metal melt and for slag, characterized in that 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 that in the interior (31) of the melter gasifier (10) below the entry site of the feed duct (9) for the metal carriers a refractory slanting wall (33) is arranged that is inclined towards the vertical line and on which there impinge the metal carriers sinking downward due to gravitational forces, and that 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.
