Classification performance of model coal mill

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 [,,, ]. The first generation of the coal mill classifier used static guide vanes to produce a swirling flow to classify the particles by centrifugal force [,,,,, ]. The modern coal mill

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.
