Abstract

Nippon Steel Corporation began pulverized coal injection at No. 1 blast furnace (inner volume: 4158m³, top pressure: 2.5×10⁴kg/m²) at Oita Works in June, 1981. Since then, both the pulverized coal injection system and No. 1 BF have been working smoothly with no serious troubles. This report describes the development of application techniques of pulverized coal injection to a large blast furnace with high top pressure and high blast temperature, and introduces the results of operation at Oita No. 1 BF in comparison with those of oil injection and all-coke operations.
