Annular rich-quench-lean gas turbine combustors with plunged holes

摘要

A combustor may include an outer liner (210) having a first group of air admission holes (250) and defining a plurality of outer liner regions (302). The combustor may further include an inner liner (212) having a second group of air admission holes (270) and defining a plurality of inner liner regions (402). The first group of air admission holes within a respective outer liner region may include a first plunged air admission hole (354) approximately axially aligned with the respective fuel injector, a second plunged air admission hole (351) approximately on the outer boundary line between the respective outer liner region and a first adjacent outer liner region, the first air admission hole being downstream of the second air admission hole, and a third plunged air admission hole (357) approximately on the outer boundary line between the respective outer liner region and a second adjacent outer liner region.
