We distinguish coking-coal rheology and blend compatibility from PCI grindability and combustion requirements.
Material characterization and acceptance
We distinguish coking coal from pulverized coal injection (PCI) feed. Coking inquiries address rheology, petrography and blend compatibility; PCI inquiries address grindability, combustion behaviour and ash chemistry. Moisture, sulphur and analytical basis remain essential to both specifications.
Process compatibility and end-use requirements
Coke production
We review fluidity, swelling behaviour, vitrinite reflectance and ash chemistry against the proposed blend; final coke strength and reactivity cannot be inferred from one coal parameter.
Blast furnace injection
We assess HGI, volatile matter, moisture, ash and sulphur against milling, drying and injection-system requirements; furnace substitution performance needs operating evidence.
Blend optimisation
We compare component analyses on consistent bases and review blend rheology and petrographic compatibility; acceptance requires agreed testing rather than arithmetic averages alone.
