摘要： 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 is formed with a purging air flow passage that injects 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 formed within an opening formation range. The opening formation range is made up of a range from the downstream end of the burner case to a plate thickness dimension of the base plate toward the upstream side, and a range from an inner circumferential surface of the burner case to the plate thickness dimension of the base plate in the radial direction.

摘要： A sound attenuator includes part of a plate forming a combustion liner and an acoustic cover defining, in conjunction with this part of the plate, a space on the outer circumferential side of the combustion liner. A restrictor that reduces a gas flow path is provided inside the combustion liner. At least one through-hole penetrating from inside the combustion liner to the space is defined in the part of the plate. At least one of the through-holes in the sound attenuator is present within a region spanning from a position of a minimum restrictor diameter of the restrictor to positions, on an upstream side and a downstream side, at a distance equivalent to a minimum restrictor radius.

摘要： A combustor includes a nozzle, a burner cylinder surrounding the outer circumference of the nozzle, and an outside flow path cylinder surrounding the outer circumference of a downstream end portion of the burner cylinder. A purge air flow path through which air flows is formed between the inner circumferential side of the outside flow path cylinder and the outer circumferential side of the burner cylinder. A tapered surface is formed in the downstream end portion of the burner cylinder such that the plate thickness of a burner cylinder-forming plate that forms the burner cylinder gradually thins toward the downstream side.

摘要： A fuel control device includes a stem fuel valve opening degree determination unit, a branch line flow rate determination unit, and a correction value determination unit. The stem fuel valve opening degree determination unit is configured to determine an opening degree of a flow rate adjustment valve of a stem fuel supply line. The branch line flow rate determination unit is configured to determine the opening degree of each flow rate adjustment valve of the branch line based on an operation situation of the gas turbine. The correction value determination unit is configured to determine a correction value of the opening degree of each flow rate adjustment valve of the branch line based on a value of a pressure difference between a fuel pressure upstream of each of nozzles connected to the branch lines respectively and a corrected fuel pressure for the fuel pressure at an outlet.
