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.

Modelling of Vertical Spindle Mills in Coal Fired Power

A mathematical model of a vertical spindle mill used in coal-fired power plant is presented. The model is developed based on a mill size mass balance (SMB) and mill global mass and energy balances. The model has been validated using data collected from a 660 MW unit during mill modelling field tests. The model can be used to perform mill dynamic performance studies, design and evaluate new
