Abstract
Provided is a combustion nozzle including a center cylinder having a cylinder shape, a middle cylinder coaxially disposed with the center cylinder and surrounding the center cylinder, an outer cylinder coaxially disposed with the middle cylinder and surrounding the middle cylinder, and a perforated plate disposed inside the center cylinder to create turbulent flow therethrough. In addition, the combustion nozzle further includes inner vanes disposed between the center cylinder and the middle cylinder and outer vanes disposed between the middle cylinder and the outer cylinder.

A combustion nozzle of a gas turbine comprising:
- a center cylinder having a cylinder shape and configured to pass air, fuel, or premix gas therethrough;
- a middle cylinder coaxially disposed with respect to the center cylinder and surrounding the center cylinder;
- an outer cylinder coaxially disposed with respect to the middle cylinder and surrounding the middle cylinder;
- and
- a perforated plate disposed inside the center cylinder and configured to create turbulent flow through the center cylinder, the perforated plate including a circular plate having a disc shape that passes through the cylinder axis of the center cylinder, the perforated plate having a plurality of flow holes configured to create the turbulent flow,
- wherein the middle cylinder is configured to create two separate flow regions outside the center cylinder, and
- wherein a length of the middle cylinder along an axial direction is greater than a length of the center cylinder along the axial direction.
