| Abstract Scope |
This paper collects relevant technical indicators of tuyere coke samples from different blast furnaces at Shougang Group across various periods. Petrographic analysis by particle size was conducted on samples from different radial positions in the hearth, exploring the distribution characteristics of unburned pulverized coal (UPC) in the samples. The concept of a "classical particle size range" for studying UPC in blast furnace hearth samples is proposed. Results indicate that UPC primarily accumulates near the raceway periphery. Furthermore, by optimizing oxygen enrichment, coal blending, and particle size control in PCI (pulverized coal injection), the proportion of UPC can be reduced during high-rate PCI operations. |
