Title:
OXYGEN SEPARATING GAS TURBINE COMBINED SYSTEM
Document Type and Number:
Japanese Patent JP2008111419
Kind Code:
A
Abstract:

To provide an oxygen separating gas turbine combined system avoiding drop of oxygen separation efficiency by using a different temperature raising means for heating material air, and improving energy efficiency.

In the oxygen separating gas turbine combined system, a gas turbine 9 and an oxygen separating device 1 separating oxygen by using a separating film made of oxide ion permeable oxide. All or part of high pressure air formed at a compression part 10 of the gas turbine 9 is heated by heat exchange and oxygen of high purity is separated by the separating film. Oxygen lean air after oxygen separation is used for heating high pressure air and driving the gas turbine 9 after temperature thereof is raised by using an auxiliary heating means.
