Iron ore sinter /pellets are redirected from the wall of the blast furnace to the center using the bell-less top charging equipment. The top gas utilization (TGU) improves from 47.5 to 49.0% (an increase of 1.5%) due to better contact of the ferrous burden with the CO-rich gas in the furnace center.
