Injection of natural gas in the blast furnace at high rates: Field experiments at Armco Steel Company. Topical technical report, January 1990-September 1992

Technical Report ·
OSTI ID:5960180
A study of the benefits of the injection of natural gas as a supplemental fuel for commercial blast furnaces is presented. Tests were carried out for sustained periods at natural gas injection levels of 150 and 200 pounds per therm (lb/thm). Average coke replacement ratios of 1.30 pounds of coke per pound of natural gas injected and productivity increases of about 10% were achieved at a gas injection rate of 200 lb/thm. The results were obtained without adverse effects on hot metal chemistry or furnace operability. The ability of natural gas to effectively replace an appreciable amount of coke should enable a decrease in coke production levels.
