An article in the February 2007 issue of Power explained that one way to improve the combustion and emissions performance of a plant is to optimize the performance of its coal pulverizers. By adding a dynamic classifier to the pulverizers, you can better control coal particle sizing and fineness, and increase pulverizer capacity to boot.
Ignition sources could be smoldering coal in the classifier, pulverizer or raw coal in the high temperature under bowl area. All efforts must be taken to prevent coal from accumulating or settling in any of the pulverizer components. Dry coal that is allowed to remain in the pulverizer system can spontaneously ignite.
