Abstract [en]

Recent years more research has been focusing on utilizing biomass in the blast furnaces (BFs). One driving force is linked to the climate change mitigation, i.e. to reduce CO2 emission from fossil reducing agents or fuels, by using biomass. The amounts of biomass that could be utilized in BF is limited by different parameters, such as metallurgical properties of reducing agents, fuel properties such as volatile content, fixed carbon and oxygen content, ash chemistry (S, Na2O, K2O, etc.). In this paper, different types of biomass products in the form of solid, liquid and gas are investigated as injectants to the blast furnace. The modelling work has been done for a BF from a Nordic country. The possible amounts of injected biomass products are presented. With the replacement ratios of pulverized coal (PC), the potential CO2emission reduction when injecting different biomass products is quantified. In addition, the strategy of using biomass at the studied iron-making plant is discussed. AISTech 2015 Proceedings © 2015 by AIST.
