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.
The reason: Operation with only one coal mill is carried out with higher load of coal dust and results in higher firing quality and thus higher rated thermal input. This is different from two-mill operation. In this mode, the rated thermal input per mill is clearly lower.
