摘要： A combustor liner (24,26) includes panels (28) joined together at a cooling nugget (30) including a bridge (32) and a lip (34) extending therefrom. The lip (34) defines a slot (36) terminating in an outlet (38). Thermal barrier coating (42) covers inboard surfaces of the panels (28) and lip (34) with a nominal thickness. The lip (34) has a distal end at the slot outlet (38) which is spaced from the coating aft of the slot less than about the coating nominal thickness.

摘要： A combustor liner (12) for use in a gas turbine engine includes a first annular panel section (42) having a forward end, an aft end and a first cooling nugget (48) located at the forward end thereof, and a second annular panel section (43) having a forward end, an aft end and a second cooling nugget (56) located at the forward end thereof. The second panel section (43) is joined at its forward end to the aft end of the first panel section (42). A first row of cooling holes (54) is located in the first cooling nugget (48), and a second row of cooling holes (54) is located in the second cooling nugget (56). A group of dilution holes (84) is located in the first panel section (42). The dilution holes (84) are located at the aft end of the first panel section (42), immediately upstream of the second cooling nugget (56). Furthermore, each one of the dilution holes (84) defines an aftmost edge, and all of the aftmost edges are axially aligned, even if the dilution holes (84) have different hole diameters.

摘要： This invention relates to fuel staged premixed dry low NO x gas turbine combustors of the type that are constructed with multiple concentric cylinders (3a-f) to which fuel manifolds (8a-e) are mounted. The cylinders (3a-f) are spaced in a staggered arrangement. Such structures of this type achieve stable combustion over a wide range of fuel-to-air ratios and low flame temperatures in the combustor resulting in low emissions of nitrogen oxides (NO x ).
摘要翻译：本发明涉及这样一种类型的燃料分段预混干式低NOx燃气轮机燃烧器，该燃烧器由安装有燃料歧管（8a-e）的多个同心圆筒（3a-f）构成。气缸（3a-f）以交错布置间隔开。这种类型的结构在燃烧空气比范围广，燃烧室内的低火焰温度下实现稳定的燃烧，导致氮氧化物（NOx）的低排放。
