Abstract

See full text

The object of the invention is a combustion method for a solid feed using a chemical loop wherein an oxygen-carrying material circulates, said method comprising at least:

    contacting the solid feed particles in the presence of metallic oxide particles in a first reaction zone (R1) operating in dense fluidized bed mode,carrying out combustion of the gaseous effluents from first reaction zone (R1) in the presence of metallic oxide particles in a second reaction zone (R2),separating in a separation zone (S3) the unburnt particles and the metallic oxide particles within a mixture coming from second reaction zone (R2),re-oxidizing the metallic oxide particles in an oxidation zone (R4) prior to sending them back to first zone (R1).
