Description

The efficiency of blast furnace operation with pulverized coal injection (PCI) by tuyeres is determined by the composition and properties of the used coals and by the quality of the ferrous burden and coke. A study in thermo balance of coals to be injected by tuyeres is carried out, and the softening and melting temperatures of coals ash are determined. The coal performance and its influence in the blast furnace operation is estimated. (Author) 7 refs
