Disclosed are fuel for injecting into a blast furnace and a method of injecting the fuel. According to the fuel for injecting into a blast furnace and the method of injecting the fuel, greenhouse gases and operation expenses can be reduced by reducing the amount of coal included in pulverized coal via use of solid cow manure, agro-livestock wastes can be converted into resources by using cow manure, i.e., agro-livestock waste, thus being advantageous in terms of an environment, high-speed reduction of iron ore can be achieved by facilitating generation of reducing gas, stable production of molten iron and efficient operation of a blast furnace can be performed by stably injecting pulverized coal and solid cow manure, i.e., heterogeneous materials having different specific gravities, into an furnace-injected fuel storage tank, and mixed injection based a desired mixing ratio can be performed by automatically controlling the degree of opening of an outlet of a cow manure hopper when pulverized coal is emitted. 고로취입용연료 및 그 취입방법이 개시된다. 본 발명의 고로취입용연료 및 그 취입방법은 고형우분을 사용하여 미분탄에 포함되는 석탄 사용량을 줄임으로써 온실가스 및 조업원가 절감이 가능하고, 농축산 폐기물인 우분을 활용함으로써 농축산 폐기물을 자원화하여 환경적인 측면에서 유용하고, 환원가스의 생성이 용이하여 철광석의 고속환원이 가능하고, 비중이 서로 다른 이종물질인 미분탄과 고형우분을 고로취입용연료 저장조에 안정적으로 취입하여 안정적 용선생산 및 고로조업의 효율적 운용이 가능하고, 미분탄 불출시 우분 호퍼의 배출구 개도를 자동조절하여 원하는 혼합비율로 혼합 취입이 가능한 효과가 있다.
