Abstract：Abstract： Coal injection into blast furnace can reduce the coke ratio, but at the same time aggravate the greenhouse gas emission and other environmental pollution problems. In recent years, new fuels replacing pulverized coal injection (PCI), such as blue charcoal, biochar, and urban organic wastes (waste plastics, waste tires, etc.) have been explored. Among them, biomass has received extensive attention because of its rich source and environmental friendliness. The carbon content in biochar is similar to that of coal, and it has the basic conditions to replace pulverized coal for blast furnace injection. The background technology of fuel injection into blast furnace was discussed, while focusing on the preparation of biochar, and the current status of biochar injection into blast furnace. The physical and chemical properties, calorific value, combustion characteristics of biochar were compared with coal. The feasibility of replacing PCI with pulverized biochar injection (PBI) in blast furnace, and prospects of PBI in blast furnace iron making were analyzed.
