Blast furnace injection of low volatile coal at Bethlehem Steel`s Burns Harbor Division

The blast furnaces at Bethlehem Steel`s Burns Harbor, Indiana plant operated with granular coal injection throughout 1995 and 1996. The coal used during 1996 was a low volatile Virginia coal. The grinding characteristics of this coal, with a Hardgrove Index of 100, helped to stabilize the operation of the coal processing system. The blast furnace process also achieved significant improvements in process stability, reaching replacement rates predicted by earlier computer simulations. Of particular note was a stabilization of wall heat flux on D furnace and the attainment of a higher coal injection rate than was projected in 1995 without unacceptable refractory wear. This paper discusses critical events and achievements in Bethlehem Steel`s switch from natural gas injection to coal injection on the C and D blast furnaces at Burns Harbor and the subsequent process results with the injection of low volatile granular coal.
