    摘要: A method and system is provided for combusting a fuel having application to a heat consuming device such as a boiler or furnace or a reactor. An oxygen-containing stream is introduced into one or more oxygen transport membranes subjected to a reactive purge or a sweep gas. The oxygen transport membrane(s) can advantageously be subjected to a reactive purge or a sweep gas passing in a cross-flow direction with respect to the membranes to facilitate separation of the oxygen. In case of a reactive purge, temperature control of the oxygen transport membrane(s) is effectuated by the use of a suitable heat sink. Further, the oxygen transport membranes can be arranged in a row and be connected in series such that retentate streams of ever lower oxygen concentrations are passed to successive oxygen transport membranes in the row. The fuel or sweep gas can be introduced in a direction counter-current to the bulk flow of the retentate streams.

    摘要: An oxygen separation and combustion apparatus such as a boiler or a nitrogen generator in which a plurality of fluid passages and oxygen transport membranes are located within a combustion chamber. The oxygen transport membranes separate oxygen from an oxygen containing gas, thereby to provide the oxygen within the combustion chamber to support combustion of a fuel and thereby to generate heat. The fluid passages are positioned to allow a portion of the heat to be transferred from the combustion to the oxygen transport membranes to heat said oxygen transport membranes to an operational temperature and a further portion of the heat to be transferred from the combustion to the fluid, thereby to heat the fluid and also, to help stabilize the operational temperature of said oxygen transport membranes. Fuel is introduced into the combustion chamber by injection or as a mixture with circulated flue gas. The fuel is introduced into the combustion chamber and the combustion products are discharged so that said combustion products flow in a direction predominantly parallel to said membranes.
