ABSTRACT:
Undesirably high and damaging temperature gradients resulting from hot spots in combustors 26 for housing a hot gas generating oxidation reaction are avoided in a construction including a combustor housing haivng a wall 32, 34, 39 with an interior surface defining a combustion space 38, 40 and an exterior surface thereof and provided with an outlet 36. A plenum 44, 80, 82 surrounds the combustor 26 and a fuel injector 50, 52 is provided for introducing a fuel to be oxidized into the combustion space 38, 40. Oxidant inlets 54 to the combustion space 38, 40 are provided and various structures including the plenum 44, 80, 82 flow cooling gas in a path about the exterior surface of the walls, 32, 34, 39 to cool the combustor housing. Trip strips 114, 118 are located on the exterior surface of the walls 32, 34, 39 and extend into the cooling gas flow path and are located to minimize the temperature gradient between points along those walls 32, 34 and 39.
