Abstract

A melter gasifier of a smelting reduction installation is charged by bringing together coal -containing material in lump form and iron carrier material (which may be hot) before and/or while they enter the melter gasifier. The ratio of the combined amounts of iron carrier material and coal-containing material in lump form is variable. The combined amounts of iron carrier material and coal-containing material in lump form are distributed over the cross section of the melter gasifier by a dynamic distributing device, and the ratio of the combined amounts of the iron carrier material and coal-containing material in lump form is set depending on the position of the dynamic distributing device.
