METHOD OF PRODUCTION OF REDUCING GAS FOR SMELTING IN BLAST-FURNACES Russian patent published in 1997 - IPC

Abstract RU 2083677 C1

FIELD: ferrous metallurgy. SUBSTANCE: the offered method of production of reducing gas from solid fuel includes supply into slag melt of oxygen-containing blast. loading of lamping coal as solid fuel, and flux is used in form of lime or limestone. Partial afterburning of reducing gas above slag melt is effected by oxygen-containing blast up to attainment of content of (CO2+H2O) in the amount of 5-15 vol.%. EFFECT: higher efficiency.
