Abstract
A gas turbine combustor forms a combustion region Rtherein by burning a premixed gas obtained by previously mixing a fuel and combustion air. The gas turbine combustor includes: a burner cylinder () in which the premixed gas passes; a film air supply port () that is provided on the burner cylinder, and supplies a film air formed into a film shape and flowing along the inner wall surface (the inner circumferential surface) of the burner cylinder (); and a cooling passage () in which a cooling air passes. The cooling air cools a back-step surface () facing the formed combustion region R. The cooling passage () includes a side from which the cooling air flows out, and the side is connected to the film air supply port ().
