Pulverized-coal injection in a 5000-m3 blast furnace

Numerous problems are encountered in the introduction of pulverized-coal injection at a 5000-m 3 blast furnace. To resolve those problems, changes are proposed in the furnace profile, the number and diameter of the air tuyeres, the batch distribution in the mouth, and the gas flux in the hearth.
