<p>A gas turbine combustor having a cooling structure improved to enhance convection cooling effect on a combustion tube and effectively suppress buckling of the combustion tube. The gas turbine combustor has the combustion tube (2) and a heat transfer promotion body (30A). The combustion tube (2) has a combustion chamber (3) therein, and compressed air (A) flows outside the combustion tube. The heat transfer promotion body (30A), which is a honeycomb structure having projecting ribs (32A, 32B), is provided on the outer peripheral surface (2c) of the combustion tube (2). The honeycomb structure is formed by connecting together hexagons, rhombuses, parallelograms, bent rectangles, or triangles.</p> |
