“…On the other hand, the most important advantage of biomass energy is that the production amount can be predicted as long as it is the raw material [7]. Similarly, it is possible to obtain uninterrupted electricity in geothermal energy [8].…”

“…Wei et al referred in (Wei et al, 2017) that the net CO 2 emission from the charcoal system used in metallurgical technologies is only about 50kg-C/t than in the conventional system with CO 2 emission about 528 kg-C/t. Jha et al in (Jha and Soren, 2017) explain that biomass is a carbon neutral source of energy where the CO 2 generated from the industrial operations like sintering has been absorbed again by the biomass and again utilized as fuel.…”

The paper deals with possibilities of low carbon technology application in metallurgy. It sums up the world wide experience with them and presents possibilities of their application in metallurgical production in view of carbon dioxide emission responsible for greenhouse effect and global warming of the Earth. It summarizes research projects in this field and presents the results and conclusion resulting from them. It is aimed at the possibilities of low carbon application in sinter and subsequently in blast furnace process. It presents research on reducibility of metallurgical ekosinter produced with share of biomass in comparison with sample of industrial one. It describes the testing methodology carried out in accordance with ISO 4695:2007. The samples were tested in reduction atmosphere created by 40% CO2 and 60% N2 simulating conditions in blast furnace aggregate at temperature 950°C. The obtained results confirmed better reducibility rate of ekosinter which reached the reduction index (dR/dt) 1.15, in comparison with industrial sinter of reduction index 0.83.

“…Sintering is an energy-intensive (1.4-2.6 MWh/t [16]) and complex process, in which a number of parameters have to be taken into account [17]. The basic fuel for the iron ore sintering process is coke breeze (CB), the use of which can be supported by substitutional fuels, e.g., anthracite [18].…”

The article presents results of the research on the use of chars produced during pyrolysis of residual biomass as a substitutional fuel in the iron ore sintering process. Such an approach allows to implement circular economy and industrial symbiosis to the iron and steel branches. The effect of the substitution of conventional coke breeze fuel used in sintering on final sinter quality and emission was examined. With regard to productivity, fuel consumption, and properties of the sinter it was shown that the share of tested biochars in fuel may be kept at 10, and up to 30 wt.%, depending on the biochar type. It was observed that with the use of the biochars, the content of iron oxide in the sinter decreased, which was advantageous. Moreover, the sinter obtained in the presence of biochars was characterized with better strength and abrasion than the sinter obtained with coke breeze-based fuel, improving the final product quality. The presence of biochar influenced the raw exhaust gas composition and resulted in a slight increase of organic and inorganic carbon compounds content, while the amount of sulfur oxides was noticeably decreased. It was concluded that the biochars may be applied in the sintering process at established share in the fuel stream.
