IMPROVED DIRECT SORBENT PREPARATION/FEED APPARATUS AND METHOD FOR CIRCULATING FLUIDIZED BED BOILER SYSTEMS

摘要

A sorbent conditioning and feed apparatus (200) for a circulating fluidized bed combustion system includes a dryer apparatus (202) configured to dry unprocessed sorbent material transported thereto from a raw storage container (304); a sorbent crushing device (204) configured to reduce the particle size of dried sorbent material discharged from the dryer apparatus (202); and a circulating fluidized bed (CFB) boiler (302) configured to receive processed sorbent material conveyed from the sorbent crushing device (204); wherein the dryer apparatus (202) utilizes an untempered hot air source diverted directly from a primary air stream input to the circulating fluidized bed boiler (302).
