摘要

This blast furnace arrangement is equipped with: a blast furnace - main body (110); starting material - loading means (111, 113), which is an iron ore and coke containing starting material (1) into the interior of the blast furnace - main body (110) over the apex thereof filling; - stream of hot air blower means (114, 115), which is a hot air stream (101) by means of a blast nozzle into the interior of the blast furnace - main body (110) blowing; as well as blast furnace - blow-in coal - feeding means (120 – 129), which the blast furnace - blow-in coal (11) by means of the blast nozzle into the interior of the blast furnace - main body (110) blowing. The blast furnace - blow-in coal - feeding means (120 – 129) bubbles a blast furnace - blow-in coal (11), which contain a content of oxygen atoms (on a dry basis) of 10 – 20 w -% and a mean pore size of 10 – 50 nm.
