Abstract
The analysis of the use of pulverized coal injection (PCI) in the practice of blast furnaces of the Russian Federation was made. It is shown that the current level of injecting of PCI is much lower than in the world’s best practices. The factors hindering the development of this direction in Russia are presented. The authors have analyzed the activities suggested in order to reduce carbon dioxide emissions from the production of iron (ULCOS program). It is proposed to enter the poly-fuel gas generators of bubble type into the blast-furnace shops for the production of hot reducing gases (HRG) for subsequent injection into blast furnaces. The calculation was made for the performance of blast furnace with volume of 1033 m3 and HRG injection of up to 400 Nm3/t of cast iron. When such HRG injection the coke savings are 100–120 kg/t of cast iron. Expected savings of coke while HRG injection of 700 Nm3/t are up to 200 kg/t of cast iron. It is proposed to create a consortium of leading metallurgical enterprises for testing the proposed technology in pilot industrial conditions.
