COMBUSTOR AND GAS TURBINE

Abstract: a combustor of the present disclosure comprises: a combustor plate that includes an upstream end surface and a downstream end surface which are orthogonal to a combustor axis; a plurality of mixing tubes which extend across the upstream end surface and the downstream end surface so as to penetrate said surfaces, and into which air is introduced from the upstream end surface side; a bump section that is formed so as to rise from the inner wall surface of the mixing tubes and that has a streamlined shape in a radial view of the mixing tubes; and a fuel injection hole having an opening that is open to the bump section to enable fuel to be injected into the mixing tubes.
