FAST FLUIDIZED FLUIDIZED BED DEVICE WITH SATURATED FLOW OF CIRCULATING SOLIDS

摘要

The invention relates to a reactor (1) for a circulating fluidized bed comprising a substantially cylindrical enclosure (10) of polyhedral section, an upper part (11) for connection to the inlet of a cyclone (2) for separating solids and a lower part (12) for connection to a pipe (4) for outputting solids from said cyclone. According to the invention, said enclosure (10) comprises re-mixing profiles (13) in the form of internal annular ribs distributed over at least a portion of its height.
