Integrated high pressure drop rotating throat for a coal ...

A rotatable throat for a coal pulverizer is improved by creating a high pressure drop in the air ports which surround the throat. The lower portions of the air port nozzles are made of vanes and relatively thin sides, and shaped to provide air entrance areas from five to six times the release points of the nozzles.

Coal Pulverizer – Power Plant | Pall Corporation

2021-11-20 · Many coal pulverizer designs do not incorporate any filtration in their lube circuits.
