PROCESS FOR OPERATING A COAL-BASED FLUIDIZED BED COMBUSTOR AND FLUIDIZED BED COMBUSTOR

摘要

part (a) of the bed material is removed in a continuous (9, 10) of the lower part of the fluidized bed (20), cooled (11), (12, 13) on a low band (a) in order to obtain a specific grain size fluidized bed, and then recycled to the fluidized bed (15, 18).
