Decarbonizing existing Blast Furnaces is a critical challenge for integrated steel plants aiming for climate neutrality. This paper introduces a technological pathway that uses thermal dry reforming of coke plant by-products and Paul Wurth Tempra for electric gas heating in a top gas recycling Blast Furnace scheme.
SMS group has developed the OXYTAR technology, which converts the...
Steel industry is in transition concerning heating methods due to requirement to reduce CO2 emissions. Use of hydrogen as a fuel in combustion for heating makes the reheating furnace a possible method to reduce use of fossil fuels. Furthermore, oxyfuel combustion increases efficiency of the heating process compared to air-fuel method. The complete combustion of the fuel is ensured by excess...
HIsarna ironmaking is a breakthrough smelting-reduction technology with the potential to reduce CO₂ emissions by about 50% when operated with coal. However, further decarbonisation of the process requires replacing fossil carbon with sustainable alternatives. In this context, biochar derived from woody biomass emerges as a promising renewable carbon carrier, provided it can be produced...
