  • A

    Brayton Cycle with Regeneration

    uses a heat exchanger called a regenerator to preheat the air-fuel mixture before it is fed to the combustion chamber using the turbine effluent as the heat source.
  • A

    regenerator

    reduces QC and QH for the cycle by the same amount. This has no effect on the power produced, but increases the

    thermal efficiency

    of the cycle.
  • Capital cost and fuel prices determine whether a regenerator is justifiable.
