Jan 23 2018 For coal-fired power plants the response time of the coal mills is critical for the overall reaction time to changing demand. Flexible operation or load following requires that the output of the plant can be made to vary in accordance with demand and in accordance with allowable ramp rates.

To summarize the coal mill controls they may be divided basically into two major categories. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
However current coal-fired power generation is in competition with renewable energy and thus generation has shifted in many countries from baseload to load following mode necessitating flexibility in power plant operations. As such frequent cycling of coal-fired power plants can cause thermal and pressure stresses.
