Mill Inerting Systems Presentation to the ASBCUG

Jun 07, 2018 Interruptions in raw coal feed. Lower feeder speeds. This occurs because a minimum airflow through the coal mill must be maintained to insure that burner line velocities are not too low to allow settling of coal in the fuel lines or burner components. Not uncommon to achieve air to fuel ratios of 3 to 5 pounds of air per pound of coal.

Coal-mill optimisation in coal-fired power stations aids

This is all controlled by the coal mill or pulveriser, and its associated feeder equipment. Operation of the coal mill can affect the ramp rate of the power station and its ability to handle rapid changes in output. For coal-fired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand
