BLAST FURNACE GRANULAR COAL INJECTION AT BETHLEHEM STEEL'S BURNS HARBOR PLANT

Abstract

This paper discusses the demonstration of the British Steel/CPC-Macawber Blast Furnace Granular Coal Injection (BFGCI) technology that was installed on the blast furnaces at Bethlehem Steel's Burns Harbor Plant in Indiana as a highly successful Clean Coal Technology project, cofunded by the U.S. Department of Energy. In the BFGCI process, granular coal (10%–30% through a 200-mesh screen) is injected into a blast furnace as a fuel supplement to decrease coke requirements, thus reducing costs. Tests run to determine the effect of process variables on furnace operations showed that granular coal works as well as pulverized coal and is easier to handle and cheaper to produce because of reduced grinding costs.
