Method of charging metal carriers to a melt-down gasifying zone
First Claim
1. 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).

Abstract
In a method of charging metal carriers which contain a portion of fines and are at least partially reduced to a melter gasifier in which a melt-down gasifying zone formed by a bed is maintained, the metal carriers and carbon carriers are fed into the melter gasifier above the level of the melt-down gasifying zone. The metal carriers descend to the melt-down gasifying zone and travel through the same forming a metal melt and producing a reducing gas by coal gasification. In order to prevent a partial discharge from the melter gasifier of the metal carriers, in particular of the fine particles thereof, when charging the same, feeding of the metal carriers into the interior of the melter gasifier is effected at a vertical distance below a dome (30) terminating the melter gasifier toward the top, gravitationally and under the formation of a strand (44), and the strand (44) is surrounded by a gas jacket (45) enclosing and accompanying the freely falling strand (44) from its level of origin (at 40) onwards over a section (46) of the fall, and in this section (46) the stand (44) is supported against expansion by the gas jacket (45).
