Classification performance of model coal mill classifiers ...

2020-3-1  The classification performance of the air classifier in a vertical coal mill determines the size of pulverized coal particles. Thus, the classification performance will influence the ignition, burning, and burnout of the coal particle, and NO x formation in the furnace as well [,,, ].

Numerical and experimental analysis of pulverized coal ...

2014-10-1  Then, the pulverized coal particles move into the classifier volume (4). In the classifier volume, the gas and coal particle mixture exits the pulverizer at a velocity of approximately 30–35 m/s. This high speed forces the coal particles to the radial region of the classifier (5). However, not all of the particles follow this process.
