Title: The startup of coal injection on Bethlehem Steel`s Burns Harbor blast furnaces

Abstract

Despite the simplicity of operation and the excellent results from natural gas injection at Bethlehem Steel, there were concerns about future supply and price stability. Furthermore, the maximum projected gas rates still required coke consumption in excess of Burns Harbor`s coke production capacity. Thus in 1990 Bethlehem Steel entered into an agreement to participate in the DOE Clean Coal Technology demonstration project by installing a granular coal injection facility at Burns Harbor. This agreement called for a facility to be constructed which was capable of processing and injecting a wide range of coal types in either granular or pulverized form. Tests were to be conducted to assess the effects of a range of coal properties, coal sizing, and injection rates on a number of key blast furnace parameters. During all the transitioning from natural gas injection to coal injection and subsequent tests it was essential that the blast furnaces maintain their historic operating performance in support of the Burns Harbor Division`s product market requirements. Unlike many coal injection facilities, the Burns Harbor installation is owned by Bethlehem Steel and the operation and maintenance from raw coal unloading through the tuyeres is the responsibility of the Blast Furnace Department. As themore » authors will discuss, the start-up of this major installation involved significant challenges, the most critical of which was maintaining historically high blast furnace operating standards while commissioning a new facility and adapting the furnace process to coal injection.« less
