Pulverizer Fineness and Capacity Enhancements at Danskammer

The rotational speed of the classifier can be varied with boiler load or with changes in coal characteristics to better match the fineness with the furnace requirements. Inherently, the rotational effects of the dynamic classifier and better fineness improve coal and air distribu- tion to the coal pipes and to the burners.

What is a dynamic classifier? - EBSCO Information Services

A classifier generally separates coarse from fine coal and a dynamic classifier has an inner rotating cage and outer stationary vanes. It is stated that in many cases, replacing a pulverizer's static classifier with a dynamic classifier improves the unit's grinding performance, reducing the level of unburned carbon in the coal in the process. ...

Dynamic classifiers: a fine way to help achieve lower ...

There have been very few conversions of UK coal mills from static to dynamic classifiers. But test experience with a dynamic classifier at Powergen's Ratcliffe-on-Soar power station has demonstrated significant fineness gain, especially at the coarse end of the particle size distribution curve, and minimal effect on mill coal throughput and operability, with greatly reduced in vibration levels.

Pulverized coal fineness is controlled by use of a Dynamic™ classifier. The rotating classifier vanes more effectively prevent larger coal particles from exiting the pulverizer, and this helps decrease the UBC levels in the flyash. Finer coal particles can also enhance fuel-bound nitrogen conversion and its subsequent reduction to
