the coal in the first place was to assist the pulverizers in their job. Unfortunately, the mills never saw the coal because the feeder was plugged. Increased moisture also decreases pulverizer performance by lowering the Btu value and causing additional coal recirculation to allow drying. Moisture Impact on Heatrate

Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner.
