Patent ID: 8518353

Claim:
A circulating dry scrubber system comprising: a circulating dry scrubber reactor configured to reduce pollutants from flue gas by passing flue gas through circulating particles of sorbent within the reactor; a particulate capture component in fluid communication with the reactor for filtering particles out of a stream of treated flue gas from the reactor; a recycle diverter connected to the particulate capture component to receive sorbent particles therefrom for separating particles into: a recycle stream connected to the reactor for reuse in the reactor, and a purge stream; and a classifier operatively connected to receive particles from the purge stream, wherein the classifier is configured to separate particles from the purge stream into: a coarse solids recovery stream connected to recover coarse solids from the classifier and divert them into the reactor, and a waste stream for disposal of fine particles from the classifier.
