| Popis: | Coke in the blast furnace experiences great changes in their properties during the blast furnace operation. Pulverized Coal Injection (PCI) into the blast furnace through tuyeres together with oxygen enrichment affect coke properties and blast furnace operation. Using coke sampler at tuyere level, coke samples were collected and analysed at various coal injection rates in the both conventional and co-axial oxygen enrichment. With the help of information obtained from coke sampling experiments, gas permeability resistance index at lower part of blast furnace (LK) and mean size variation of coke were predicted and matched well with the measurements. |
