As feed rate decreased, fineness improved. Note that better than ±10% fuel balance is not achieved until better than 70% passing 200 Mesh is achieved. When >10% fuel imbalance is observed, burner lines with higher fuel flows typically have less desirable fineness. Burner lines that have less fuel typically have better coal fineness.
