Title:
GAS TURBINE COMBUSTOR
Document Type and Number:
WIPO Patent Application WO/2022/255334
Kind Code:
A1
Abstract:
This gas turbine combustor is provided with: a cylinder body that defines a combustion chamber; an air passage for supplying air to the combustion chamber; and a resonator including an opening open to the air passage.
The air passage includes: an upstream region along the outer circumferential surface of the cylinder body; a downstream region that is provided along the inner circumferential surface of the cylinder body and that is disposed at a first side of the combustion chamber in the axial direction; and a direction change region that connects the upstream region and the downstream region in the radial direction of the cylinder body, and that adjoins the upstream region in such a manner that a cross-sectional area thereof perpendicular to the axial line changes from the direction change region to the upstream region. The opening is open to a space at the downstream side of the upper region in the air passage.
