Experience in Coke Preparation for Blast-Furnace Smelting. Part 2

One element of the coke preparation process for this blast-furnace smelting technique involves increasing the minimum size of the skip coke to 28-30 mm, separating out the nut coke (> 15 mm) via a screen, and then charging the blast furnace with the nut coke after mixing with the iron-ore portion of the charge [ 25 ].

Direct Emissions from Iron & Steel Production - Greenbiz

Crude iron is produced by the reduction of iron oxide ores in a blast furnace. The combus tion of coke, petroleum coke, or coal provides the carbon monoxide (CO) to reduce the iron oxides to iron and provides additional heat to melt the iron and impurities. Carbon dioxide (CO 2) emissions are produced as the coal/coke
