Abstract
A combustor is equipped with a burner case, and a base plate spreading from a downstream end of the burner case in a radial direction. The base plate defines a purging air space at an upstream side of the base plate. The combustor includes a purging air flow passage configured to inject purging air in the purging air space to a downstream side relative to the base plate. An outflow opening of the purging air flow passage is defined within at least one of a radial range from an inner circumferential surface of the burner case and an axial range from the downstream end of the burner case.
