Anthracite Coal Specification (High carbon coal mainly for metallurgy, steel, carbon filters, and industrial uses) Parameter Unit Typical Anthracite Value Fixed Carbon (adb) % > 80–90% Calorific Value (GCV/AR) kcal/kg 7,800–8,500+ kcal/kg+ Ash (adb) % 8–12% (premium <8%) Volatile Matter (adb) % 7–12% (very low) Total Moisture (AR) % 3–6% Sulphur (adb) % ≤ 0.7% (low-sulphur) Size mm Common: 0–6 mm, 6–22 mm, 22–50 mm Density g/cc 1.4–1.7
Anthracite coal is the highest rank of coal, known for being hard, brittle, and shiny with a high carbon content and low volatile matter. It is a clean-burning fuel with a high heat value, used in applications like steel production, home and industrial heating, and water filtration, although it is rare and more expensive than other types of coal.
