CLC INSTALLATION COMPRISING A SOLID / SOLID SEPARATOR WITH INTEGRATED CYCLONIC ENCLOSURE

摘要

The present invention relates to a solid / solid separator of a chemical loop combustion installation (CLC), comprising an enclosure successively formed by: - a cyclonic upper part (17, 18) comprising a supply line (16) for a gas mixture comprising particles of an oxygen-carrying solid and unburnt particles from a reduction reactor of the installation, and an outlet pipe (31) for a gas flow comprising the majority of the particles d 'unburnt; - A central cylindrical part (20) extending the cyclonic part, and configured to operate a separation by diluted phase elutriation; - a lower particle collection part (21, 22) into which the middle part opens, the lower part comprising a main injection system for a first fluidizing gas (28), being configured to comprise a dense fluidized bed of particles (25), and comprising a discharge pipe (27) of a flow mainly comprising the particles of the oxygen carrier.
