classifier offers increased flexibility to take advantage of a wide (and sometimes lower quality) range of coal. For existing equipment, the DSVS classifier helps in low-NO X burner retrofits by providing higher fineness that reduces unburned carbon. Fineness levels can be adjusted by changing the classifier speed while the mill is on-line.

of coal. For existing equipment, the DSVS classifier helps in low-NO x burner retrofits by providing higher fineness that reduces unburned carbon. Fineness levels can be adjusted by changing the classifier speed while the mill is on-line. The compact DSVS classifier can be easily installed on existing B&W and non-B&W pulverizer equipment.
