Abstract

Abstract

A numerical simulation of the oxygen blast furnace is established in this paper.The results show that fuel consumption can be reduced by 5% when top gas of the oxygen blast furnace is recycled and CO₂ emissions can be reduced by more than 56% when CO₂ in the top gas is stored and utilized.Industrial tests of the oxygen blast furnace indicate that,order to achieve low-cost production,four key problems are to be solved,namely,high injection efficiency,full-process control,recycled gas heating,CO₂ removal from the top gas,CO₂ storage and utilization.Meanwhile,proposals for development of the oxygen blast furnace iron-making process are put forward.
- oxygen blast furnace,
- top gas,
- carbon dioxide,
- efficient injection,
- fuel consumption reduction
