Abstract
The invention relates to an annular combustor (13) for a gas turbine (10), into which combustor (13) burners (14, 15) open on an inlet side, and which combustor (13) extends in the axial direction from the inlet side to an outlet side (33) and is lined on the insides with cooled liner segments (16, 17) for protection from the hot gases. In such a combustor, increased mechanical stability and flexibility in design and also simplification in manufacture and fitting are achieved by the liner segments (16, 17) being subdivided in the axial direction into a plurality of parts (16, 17) arranged one behind the other.
Claims10
An annular combustor for a gas turbine, comprising:
- a wall, an inlet side, and an outlet side, the inlet side configured and arranged to accept burners opening on the inlet side, the combustor extending in an axial direction from the inlet side to the outlet side, cooled liner segments lining insides of the wall for protection from hot gases;
- wherein the liner segments are subdivided in the axial direction into a plurality of non-overlapping and angled parts arranged one behind the other;
- and
- a plurality of segment carriers, the liner segments being fastened to the segment carriers, the segment carriers being subdivided in the axial direction into a plurality of separate, detachably connected parts, each having substantially the same length as its corresponding linger segment, at least one junction of adjacent segment carriers forming together a wedge shape.
