Combustor assembly with a deflector in between swirlers on the base portion

1. A combustor assembly comprising:

a plurality of swirlers through which a first fluid that is a part of a fluid discharged from a compressor passes;

an annular shaped base portion, in which the plurality of swirlers are provided, comprising a first through hole formed between one swirler and another swirler from among the plurality of swirlers so that a second fluid that is another part of the fluid discharged from the compressor and different from the first fluid passes through the first through hole; and

a deflector provided in the annular shaped base portion between the one swirler and the another swirler so as to face the first through hole, the deflector changing a moving direction of the second fluid from the first through hole in a lengthwise direction of the combustor assembly to a radial direction both toward a center of the annular shaped base portion and away from the center of the annular shaped base portion,

wherein the deflector comprises a pair of elongated opposing supporters attached to and supported by the annular shaped base portion and a direction switching portion extending from one of the pair of elongated opposing supporters to the other of the pair of elongated opposing supporters, wherein

the pair of elongated opposing supporters are elongated in the radial direction of the annular shaped base portion and arranged next to each other in a circumferential direction of the annular shaped base portion so that two opposing openings are formed with one of the opposing openings facing the center of the annular shaped base portion and the other of the opposing openings facing away from the center of the annular shaped base portion, wherein each of the pair of elongated supporters extends from a radially inner edge of the direction switching portion to a radially outer edge of the direction switching portion, and

the second fluid that has passed through the first through hole is moved between the direction switching portion and the annular shaped base portion, and the moving direction of the second fluid changes to the radial direction both toward the center of the annular shaped base portion and away from the center of the annular shaped base portion, and the second fluid moves in the radial direction along the pair of elongated opposing supporters.

2. The combustor assembly of claim 1 , wherein the deflector comprises a third through hole formed in the direction switching portion, the third through hole being disposed outside of a contacting portion of the direction switching portion,

wherein the contacting portion is a portion that the second fluid contacts on the direction switching portion in the lengthwise direction of the combustor assembly.

3. The combustor assembly of claim 1 , wherein centers of the plurality of swirlers and a center of the first through hole are spaced apart a predetermined distance from the center of the annular shaped base portion.

4. The combustor assembly of claim 1 , wherein the deflector is formed so as to be at least partially curved.

5. The combustor assembly of claim 1 , wherein each of the plurality of swirlers has a dual structure of inlet.

6. The combustor assembly of claim 5 , wherein the dual structure of inlet includes a first inlet formed inside the each of the plurality of swirlers to form a central recirculation zone and a second inlet formed outside the first inlet to evenly inject the first fluid from the compressor.

7. A combustor assembly comprising:

a plurality of swirlers through which a first fluid passes;

an annular shaped base portion in which the plurality of swirlers are provided, the annular shaped base portion comprising a first through hole formed between one swirler and another swirler from among the plurality of swirlers so that a second fluid passes through the first through hole; and

a deflector provided in the annular shaped base portion between the one swirler and the another swirler, the deflector comprising a pair of elongated opposing supporters attached to and supported by the annular shaped base portion and a direction switching portion extending from one of the pair of elongated opposing supporters to the other of the pair of elongated opposing supporters,

wherein the pair of elongated opposing supporters are elongated in a radial direction of the annular shaped base portion and arranged next to each other in a circumferential direction of the annular shaped base portion such that two opposing openings are formed with one of the opposing openings facing a center of the annular shaped base portion and the other of the opposing openings facing away from the center of the annular shaped base portion, wherein each of the pair of elongated supporters extends from a radially inner edge of the direction switching portion to a radially outer edge of the direction switching portion,

wherein the second fluid that has passed through the first through hole is moved between the direction switching portion and the annular shaped base portion, and the moving direction of the second fluid changes to the radial direction both toward the center of the annular shaped base portion and away from the center of the annular shaped base portion, and the second fluid moves in the radial direction along the pair of elongated opposing supporters,

wherein the pair of elongated opposing supporters and the direction switching portion form a single unitary structure, and

wherein each of the pair of elongated opposing supporters is connected to a respective circumferential edge of the direction switching portion.
