Exploration and Practice of Improving the Ratio of Blast Fur-nace Bituminous Coal under the Background of"Dual Carbon"
In the context of"dual carbon",research on independent carbon reduction by enterprises is crucial.In order to re-duce the consumption of scarce anthracite resources,increasing the proportion of bituminous coal injection into blast furnaces has become an important measure.Through careful research on the performance of coal injection,it was found that there are performance differences between the main types of coal injection.Therefore,it is necessary to take measures such as control-ling the oxygen content of the powder making system and the temperature of the mill to ensure the safe operation of the injec-tion powder making system.At the same time,it is necessary to strengthen the adjustment and matching of the upper and lower parts,promote the reasonable distribution of gas flow,and compensate for the adverse effects that may be caused by the in-crease in bituminous coal ratio.Through these efforts,the goal of achieving a bituminous coal ratio of over 50%has been suc-cessfully achieved,ensuring stable and smooth blast furnace conditions,and achieving good technical and economic indicators.
