Abstract
In a method of charging metal carriers which contain a portion of fines and are at least partially reduced and carbon carriers to a melter gasifier (,) in which a melt-down gasifying zone (,) is maintained, the metal carriers and the carbon carriers are fed into the melter gasifier (,) above the level of the melt-down gasifying zone (,) and 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 of the metal carriers from the melter gasifier (,) during the charging of the same and to be able to achieve uniform distribution of the carbon carriers and the metal carriers, both the carbon carriers and the metal carriers are introduced into the melter gasifier centrally above the melt-down gasifying zone (,), preferably gravitationally, with a central strand (,) of metal carriers being formed which is peripherally surrounded by a jacket strand (,) formed by the carbon carriers.
