Carbon buildup in a turbine engine including a compressor 16 coupled to a turbine wheel 22 mounted for rotation about an axis and having a nozzle 24 disposed to direct gas at the turbine wheel 22 to drive the same, an annular combustor 26 disposed about the axis and in fluid communication with the nozzle 24 and having a radially inner wall 32, a radially outer wall 34 and a generally radially extending wall 46, a plurality of fuel injectors 48, a compressed air plenum 42, 44, 45 surrounding the combustor 26, a plurality of circumferentially spaced apertures 66 in the radial wall 34 and a cooling strip 68 for directing air passing through the apertures 66 along the radial wall 39 is reduced by locating the apertures 66 closely adjacent the radially outer part of the radial wall 39 and locating the cooling strips 68 to direct air passing through the apertures 66 inwardly as at 72 along the radial wall 39.
