Classification performance of model coal mill classifiers ...

2020-3-1 · The classification performance of a model coal mill classifier with non-swirling and swirling inlet conditions of the bottom incoming flow was experimental and numerically studied. The PIV measurements showed that under different inlet conditions, the flow fields adjacent to two neighboring blades were very different.

Derivation and validation of a coal mill model for control

2012-5-1 · The paper presents development and validation of a coal mill model to be used for improved mill control, which may lead to a better load following capability of power plants fired by pulverized coal. The model is relatively simple, yet it captures all significant mill dynamics. The model is validated using data from four mills of a similar type ...
