METHOD FOR PRODUCING LIQUID PIG IRON |
摘要 |
<p>Process and apparatus for producing liquid pig iron or primary steel products from iron-containing material in lump form in a fusion gasifier (1), in which, with lump coal and oxygen-containing gas being fed in, and with simultaneous formation of a reduction gas, the iron-containing material is fused, lump coal being fed to the fusion gasifier (1) from above and, together with the iron-containing material, forming a fixed bed (6) in the fusion gasifier (1) and thereby giving off its fraction of volatile hydrocarbons into the dome space (11) located above the fixed bed (6), and pulverized-fuel burners (15) being directed obliquely from above towards the surface of the fixed bed (6). The operation of the pulverized-fuel burners (15) is in this case controlled in such a way that the combustion of the carbon fraction of the carbon carriers in fine particle form takes place in a proportion of at least 40% to form CO2.</p> |
