modelling of vertical spindle mills in coal fired power plants

G. Fan, N. Rees. Published 1994. Engineering. 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 mill dynamics on power plant …
