QUENCH JET ARRANGEMENT FOR ANNULAR RICH-QUENCH-LEAN GAS TURBINE COMBUSTORS

摘要

A combustor (26) includes an outer liner (28) having a first row (50) and a second row of circumferentially distributed air admission holes penetrating therethrough. The combustor (26) further includes an inner liner (30) circumscribed by the outer liner (28) and having a first row (52) and a second row (56) of circumferentially distributed air admission holes penetrating therethrough. The combustor (26) further includes a plurality of fuel injectors (44) extending into the combustion chamber (32) and configured to deliver an air-fuel mixture to the combustion chamber (32). Each of the plurality of fuel injectors (44) are associated with two air admission holes in the first row (50) of the outer liner (28), two air admission holes in the first row (52) of the inner liner (30), four air admission holes in the second row (54) of the outer liner (28), and two air admission holes of the second row of the inner liner (30).
