摘要： A combustor (3) includes a plurality of first burners extending along an axis (P) and arranged at intervals in the circumferential direction, a base plate (31) having support openings configured to support the plurality of first burners and a plurality of through-holes (34) through which base plate air flows toward a downstream side, a plurality of extension pipes supported by the base plate (31) to correspond to the first burners and configured to guide a pre-mixed gas ejected from the first burners toward the downstream side, and a base plate air guide section (35) configured to change a direction of at least some of the base plate air ejected from the through-holes (34) at a downstream side of the base plate (31).
