Abstract

See full text

To suppress separation of air flows in air holes that are positioned in the outermost circumferential row in an air hole plate, but are far from a turn guide. A gas turbine combustor includes: an inner cylinder forming a combustion chamber; an outer cylinder forming a cylindrical outer circumference flow path through which compressed air flows, between the outer cylinder and the inner cylinder; an end cover closing an end portion of the outer cylinder; an air hole plate having air holes introducing the compressed air passed through the outer circumference flow path, into the combustion chamber; a plurality of fuel nozzles injecting a fuel into the combustion chamber via the air holes; a turn guide provided to the inner cylinder or the air hole plate and guiding a turn of the compressed air passed through the outer circumference flow path; and an auxiliary guide provided at an outer circumferential portion of a surface of the air hole plate facing the fuel nozzles, so as to be positioned on an inner circumference side with respect to the turn guide.
