Gas turbine combustor flame holder

A combustor comprising:

• a first nozzle which extends along an axis and injects fuel toward a downstream side;
• a flame stabilizer which covers a downstream-side end portion of the first nozzle from an outer periphery side;
• and
• a plurality of second nozzles arranged at first intervals in a circumferential direction around the axis on the outer periphery side of the flame stabilizer,
• wherein the flame stabilizer has a cone portion expanding in diameter toward the downstream side from the upstream side, and a flange portion extending radially outward from a downstream-side end edge of the cone portion,
• wherein a penetrating portion which penetrates the flange portion in an axial direction is formed in at least the flange portion,
• wherein the combustor further comprises:
• an adjustment plate which covers the penetrating portion from the downstream side, and
• wherein an adjusting penetration portion having an opening area smaller than an opening area of the penetrating portion and communicating with the penetrating portion is formed in the adjustment plate.
