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.
An area of power plant control that has received much less attention from mod elling and control specialists is the coal mills. This is in spite of the fact that it is now accepted that coal mills and their poor dynamic response are major factors in the slow load take-up rate and they are also a regular cause of plant shut-down Maffezzoni, 1986.

In the operation of a coal fired electric power plant, coal is fed to a pulverizer mill where it is finely ground for mixture with the primary air flow and transported to the burners. In many cases, the inlet hot and cold air flow mix is varied by damper positioning to hold a desired mill exit temperature for the primary air and coal mixture.
Pulverisation of coal by attrition and by impact of hard balls Speed reduction achieved by gear train consisting of reduction gear box and large spur gear. Coal can be fed and removed from both sides of the mill. Half mill operation for partial loads allowed. Input coal size 25 mm white output is 70 to 90 microns

Riley Powers engineering design was limited primarily to the boiler systems and included the following Riley Power Scope
excess air. Station service power will decrease with drier coal due to a decrease in fan power and mill power. The combination of all these effects caused by firing drier coal will result in an improvement in boiler efficiency and unit heat rate, primarily due to the lower stack loss and lower station service power.

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.
