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 ...

Coal Mill - an overview ScienceDirect Topics

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.

A multi-component model for the vertical spindle mill ...

10/03/2016  Vertical spindle mills (VSMs) are widely utilised in coal power plants that account for more than 40% of the electrical energy generated worldwide. These mills can consume up to 1% of the gross power generated by the plant; and hence, present a good scope for optimisation. However, optimisation requires better understanding of the operation of these mills and reliable models to be used for ...
