Patent ID: 8281598

Claim:
A gas turbine combustion chamber, comprising: a flame tube, which is made of a ceramic material and circumferentially divided into several circumferential elements; a plurality of axial flanges connecting the circumferential elements; a plurality of articulated coupling elements supporting the flame tube on a combustion chamber casing; wherein each of the articulated coupling elements has a first end and a second end, the first end pivotally attached to the combustion chamber casing at a first axial position of the combustion chamber and the second end pivotally attached to the plurality of axial flanges at a second axial position of the combustion chamber different from the first axial position of the combustion chamber such that different thermal expansions between the combustion chamber casing and the flame tube cause the articulated coupling elements to articulate with respect to the combustion chamber casing and the flame tube to accommodate the different thermal expansions.
