The Organization of Iron Ore Agglomerate and Pellets Production with Reduced Environmental Impact
(Baltija Publishing, Riga, Latvia, 2023) Boiko, Maksym M.; Petrenko, Vitalii O.
ENG: Purpose. The steady rise in the cost of traditional energy resources and their negative impact on the environment is leading to an increase in the share of renewable energy sources worldwide. The use of biomass for energy generation based on modern technologies is environmentally safer compared to the energy use of traditional organic resources such as coal. A significant reserve for increasing the use of energy from biomass is concentrated in the metallurgical industry, including the production of pelletised iron ore. Research has been carried out to study the impact of different types of biomaterials on the sintering process of iron ore and the quality of the resulting sinter. The study found that, provided that the process performance and sinter quality are maintained at the appropriate level, it is possible to replace up to 25% of coke fines with charcoal and up to 50% with walnut shells. An analysis of the use of sunflower husks as an alternative fuel was carried out by adding them to the already installed pellet firing system for the grate-tubular kiln-ring cooler installation. It was found that when replacing up to 50 % of natural gas with sunflower husks, the quantitative and qualitative indicators of pellet production remained at the baseline level.
