Pulverizers, also called mills, are used by many industries to grind solids to a fine powder. Performance of coal mills at power plants is critical to:
- Combustion efficiency/heat rate
- NOx & CO reduction
- Unit availability/power output.
Optimization of the flow patterns of both air and coal entering, within, and exiting a mill is an important part of plant performance. CFD modeling, lab modeling, and field testing are all used by ASC in the optimization process.
