Abstract
Dominating globally and within Ukraine, the blast-furnace practice for iron production requires iron ore sintering preparation wherein the significant amount of fossil fuel is consumed, accompanied by harmful emissions into the environment. Pursuing the purpose to mitigate this negative impact, we address the promising direction of biomass utilisation for a partial replacement of fossil fuels in iron ore sintering. This paper considers the benefits of fossil fuels substitution with biomass, the world practice of biomass utilisation in iron ore sintering and the scope of the biomass energy potential in Ukraine. The study for obtaining sinters with the use of raw biomass fuels (sunflower husk, walnut shell) and charcoal has been carried out via lab-scale sintering pot. The influence of various biomaterials types on the process of iron ore sintering have been investigated and the obtained sinter quality in comparison with the conventional types of the fuels allows establishing the feasibility of replacing 25 % of coke breeze by charcoal or by walnut shell. The sunflower husk application is possible if preliminary preparation of the material for increasing bulk density is assumed to be carried out, for instance, by pressing.
Highlights
Steel production in 2017 amounted approximately 1691.2 million tons, and according to the reported demand [1], in the nearest future this production will increasingly grow
In the Figures presented below anthracite, charcoal, walnut shell (WSH) or sunflower husk (SFH) are analysed individually in each case but referred generally as fuel
4 Conclusions The review in this work shows the possibilities of efficient biomass utilisation in the process of iron ore sintering
Summary
Steel production in 2017 amounted approximately 1691.2 million tons, and according to the reported demand [1], in the nearest future this production will increasingly grow. Higher prices on conventional energy resources and their negative impact on the environment increase the share of renewable energy in the world. One of the most promising types of renewable energy sources is biomass, which occupies the fourth place among fuels by value. Biomass accounts for about 1.4 billion toe, which is about 14 % of the total primary energy consumption in the world. In the EU energy plans, the task is to increase the share of the energy produced from renewable energy sources in gross final energy consumption of up to 20 % by 2020, including those from biomass of up to 14 %. According to the Bioenergy Association of Ukraine, the total potential of biomass energy was 20.2 million toe in 2015. The main constituents of this potential were the by-products of crop
