Claim 4:
5. A combustor comprising:
a combustion tube which has a tubular shape around an axis and is able to burn fuel;
a primary fuel nozzle which is able to inject a primary fuel in a direction toward a distal end of the combustion tube in an axial direction along the axis, inside the combustion tube;
a secondary fuel nozzle which is attached to the combustion tube at a position closer to the distal end of the combustion tube than the primary fuel nozzle and is able to inject a secondary fuel in a radially inner direction with respect to the axis, inside the combustion tube;
a fuel manifold which is disposed external to the combustion tube, has an annular shape with respect to the axis, and defines a fuel space which is able to temporarily store the secondary fuel and is in communication with the secondary fuel nozzle; and
a support which supports the fuel manifold with a gap extending radially from the combustion tube,
wherein:
the support has a support plate which is separated from the combustion tube by the gap and spreads in a circumferential direction with respect to the axis, and a support leg which is attached to the combustion tube and supports the support plate to define the gap between the support plate and the combustion tube;
the fuel manifold is disposed on a radially outer side of the support plate and is supported by the support;
the secondary fuel nozzle and the fuel manifold are disposed at different positions with respect to the axial direction; and the secondary fuel nozzle is axially aft of the support.
