Carbon Emission Reduction Effect of HyCROF and Practical Demonstration
China Baowu has developed the Hydrogen-enriched Carbon Recycling Oxygenate Furnace(HyCROF)process based on the BF low-carbon ironmaking technology,aiming to fully utilize carbon chemical energy through carbon recycling.Furthermore,hydrogen is used to replace the carbon in the reduction process,and electricity is used to replace carbon for stock heating with the purpose of significant reduction of carbon emission.To verify the feasibility of HyCROF process tech-nology concept and carbon reduction effect,Baowu Steel renovates the existing 430 m3 BF to an experimental platform of in-dustrial scale HyCROF,by which a lot of experimental researches are conducted.The research results show that:(1)Hy-CROF process is efficient,safe and stable;it runs smoothly and tolerates great fluctuation of furnace condition,additionally much less reducing agents need to be used;(2)HyCROF process stands out for its remarkable carbon emission reduction effect;both the solid fuel consumption and the carbon rate can decrease by 30％when it works under carbon recycling,and the solid fuel and carbon consumption can decrease by about 37％if hydrogen-enrichment is applied additionally.
