Biomass is renewable and carbon neutral. Biochar, derived from the carbonization of biomass, is a kind of solid fuel with excellent properties. Utilization of biomass in ironmaking process as heating agent and reducing agent contributes to energy conservation and emission reduction, and can partially replace for coal and coke. Research status of the utilization of biomass in ironmaking process is discussed. Application prospects of biomass energy in ironmaking process are analyzed, and a novel bioenergy auxiliary ironmaking system is suggested, which is meaningful for the effective use of biomass and for decreasing the consumption of fossil fuels, namely metallurgical coal and coke.
