CA 2432745

An oxygen separation and combustion apparatus (1; 2; 3) in which fluid passages (18, 20, 22, 23) and oxygen transport membranes (12, 14, 16) are located within a combustion chamber (10). The oxygen transport membranes (12, 14, 16) separate oxygen to provide the oxygen for combustion of a fuel within the combustion chamber (10). The fluid passages (18, 20, 22, 23) are positioned to allow a portion of the heat of combustion to be transferred to heat the oxygen transport membranes (12, 14, 16) to an operational temperature and to heat the fluid, thereby to help stabilize the operational temperature of said oxygen transport membranes (12, 14, 16). The fuel is introduced into the combustion chamber (10) and the combustion products are discharged so that said combustion products flow in a direction predominantly parallel to said membranes (12, 14, 16).

L'invention concerne un dispositif pour la s~paration et la combustion de l'oxyg­ne (1; 2; 3). Des passages de fluide (18, 20, 22, 23) et des membranes de transport de l'oxyg­ne (12, 14, 16) se trouvent dans une chambre de combustion (10). Les membranes (12, 14, 16) s~parent l'oxyg­ne pour fournir l'oxyg­ne n~cessaire ~ la combustion d'un combustible dans la chambre de combustion (10). Les passages de fluide (18, 20, 22, 23) sont plac~s de mani­re ~ permettre le transfert d'une partie de la chaleur de la combustion pour le chauffage des membranes (12, 14, 16) ~ une temp~rature op~rationnelle, et pour le chauffage du fluide, contribuant ainsi ~ stabiliser la temp~rature op~rationnelle des membranes (12, 14, 16). Le combustible est introduit dans la chambre de combustion (10) et les produits de combustion sont ~vacu~s dans une direction principalement parall­le auxdites membranes (12, 14, 16).
