PARTICLE SEPARATION DEVICE FOR CHEMICAL LOOPING COMBUSTION LOOP

摘要

The invention relates to a chemical looping combustion device which uses a solid fuel that generates particles of unburned residues and which employs oxygen-carrying particles, such as metal oxides. The device comprises at least one combustion zone and a separator for separating the particles contained in a gaseous mixture originating from the combustion zone. The separator comprises at least one enclosure (1) including an intake passage (4) for the mixture, a discharge passage (5) located in the lower part of the enclosure and an outlet passage (6) located in the upper part of the device, the intake and discharge/outlet parameters being selected in order to create a dense phase in the lower part of the enclosure and a diluted phase in the upper part thereof. The invention also relates to a combustion method using the device of the invention.
