ABSTRACT:
Existing combustors have the tendency to emit emissions and require a large quantity of cooling air to retain or extend the life of the components to a reasonable life expectancy. The present combustor reduces the emissions emitted therefrom, requires a reduced quantity of cooling air while resulting in a high heat transfer cooling rate extending the life expectancy of the components. The combustor construction includes an interior liner having a plurality of angled holes extending therethrough arranged in a preestablished pattern defining a centroid and an exterior liner having a plurality of holes extending therethrough at about a 90 degree. At least a portion of the plurality of holes in the exterior liner being radially aligned with the centroid of the plurality of holes in the interior line.
