Abstract:
A method which comprises:(a) charging metal carriers to a melter gasifier (10) having a melt-down gasifying zone (11) formed by a bed, said carriers containing: a portion of fines, and said metal carriers being at least partially reduced;(b) Feeding the metal carrier and carbon carriers into the melter gasifier (1) above the level of the melt down gasifying zone (11), so that said carriers descend to the melt-down gasifying zone (11) and travel through said zone to form a metal melt;(c) Producing a reducing gas by coal gasification with supply of oxygen in the lower region of the melter gasifiers at a vertical distance below the dome (3); and(d) Feeding the metal carriers into the interior of the melter gasifier at a vertical distance below a dome terminating the melter gasifier (10) toward the top gravitationally under the formation of a strand (44); and(e) surrounding the strand (44) by a gas jacket (45); and(f) enclosing and accompanying the freely falling strand (44) from its level of origin (40) onwards over a section (46) of the fall; and(g) supporting the strand (44) in section (46) against expansion by the gas jacket (45).
