SUMMARY:Development of biomass utilization technology in blast furnace for reducing CO2 in ironmaking process
DESCRIPTION:Carbon dioxide emission reduction in the steelmaking process has been raised as an important issue according to greenhouse gas emission regulations. Among them, the use of biomass resources, which are carbon-neutral materials, is expected as a way to solve environmental problems. Therefore, a study was conducted to utilize biomass in a blast furnace by replacing coke and pulverized coal. First, the basic properties of 10 candidate groups were investigated to evaluate the feasibility of using biomass in a blast furnace, and the biomass for utilize in a blast furnace was selected in consideration of the calorific value and energy density. Iron-Bearing Biomass Coke (IBC), produced by mixing coal, torrefied biomass and iron ore, was used to partially replace coke with biomass. Evaluation for strength and reactivity must be preceded for the input of IBC in a blast furnace. Therefore, Shatter Index (SI) and Coke Reactivity Index (CRI) were evaluated, and the upper area of the blast furnace was simulated using the Shaft Inner-reaction Simulator (SIS). In addition, the combustion characteristics according to the mixing ratio of pulverized coal and biomass were investigated in order to partially replace pulverized coal with biomass. The combustibility of biomass was evaluated by a combustion test using a Drop Tube Furnace (DTF). The effect of using biomass in the blast furnace was investigated, and the following conclusions were drawn. When coke and pulverized coal are partially replaced with biomass, gas utilization and combustibility are improved. As a result, it is possible to reduce greenhouse gases emitted from the blast furnace through the use of biomass.
