Abstract [en]
For an integrated steel plant, the blast furnace (BF) is the most energy intensive process unit in which coke and pulverized coal (PC) are used as reducing agents and energy carriers, leading to huge amount of fossil CO2 emission. Recent years, the steel industry has been putting much effort to reduce CO2 emissions especially for BFs. Biofuel is considered as one shortterm solution for CO2 emission reduction especially via the tuyere injection into BFs to replace PC. Much work has been carried out to inject wood charcoal in BFs due to the fact that the wood charcoal has the similar properties as PC [1]. However, the availability of forestry wood and high price of wood charcoal limit the charcoal’s utilization in BFs. So far, the charcoal injection is only realized in small scale BFs in Brazil.
