摘要:
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).
