Combustion chamber of a combustion system
View Patent ↗A combustion chamber of a combustion system comprises a combustion space, a support structure, a heat shield, and at least one through-opening. The heat shield has at least two segments, and each segment has an edge region, a gap communicating with the combustion space being formed between edge regions of adjacent segments, and a retaining device. The adjacent segments include a support element disposed in a bottom region of the gap. The retaining device fixes the respective liner element on the support structure via the respective support element. The at least one through-opening communicates with the gap so as to enable a cooling gas to flow through the through-opening. The at least one through-opening is disposed in at least one of the respective edge region and the support element at the bottom region of the gap.
1. A combustion chamber of a combustion system, the combustion chamber comprising: a combustion space;
a support structure;
a heat shield with at least two segments, each segment including a liner element facing the combustion space and having an edge region, a gap communicating with the combustion space being formed between edge regions of adjacent segments, each of the liner elements being mounted to a support element disposed in a bottom region of the gap, and each of the heat shield segments including a retaining device fixing an edge region of the respective liner element on the support structure via the respective support element;
at least one through-opening communicating with the gap so as to enable a cooling gas to flow through the through-opening into the gap thereby cooling a respective one of the edge regions facing the gap, wherein the at least one through-opening is disposed in at least one of the respective edge region and the support element at the bottom region of the gap wherein the retaining device has a flange region, and wherein the edge region of the respective liner element fits under the flange region.
2. The combustion chamber as recited in claim 1 , wherein at least one of the edge region and the support element have a thermal barrier coating.
3. The combustion chamber as recited in claim 1 , wherein the at least one through opening includes a row of through-openings extending parallel to the gap.
4. The combustion chamber as recited in claim 1 , wherein the liner element has at least one cooling rib disposed on a side of the liner element facing away from the combustion space.
5. The combustion chamber as recited in claim 1 , wherein the at least one throughopening extends at an angle to the gap so to create a predefined cooling gas flow.
6. The combustion chamber as recited in claim 1 , wherein the liner element has a rounded transition region between the gap and the combustion space.
7. The combustion chamber as recited in claim 1 , wherein the combustion system is a gas turbine.
8. A combustion system, comprising:
a combustion chamber that includes:
a combustion space;
a support structure;
a heat shield with at least two segments, each segment including a liner element facing the combustion space and having an edge region, a gap communicating with the combustion space being formed between edge regions of adjacent segments, each of the liner elements being mounted to a support element disposed in a bottom region of the gap, and each of the heat shield segments including a retaining device fixing an edge region of the respective liner element on the support structure via the respective support element;
at least one through-opening communicating with the gap so as to enable a cooling gas to flow through the through-opening into the gap thereby cooling a respective one of the edge regions facing the gap, wherein the at least one through-opening is disposed in at least one of the respective edge region and the support element at the bottom region of the gap wherein the retaining device has a flange region, and wherein the edge region of the respective liner element fits under the flange region.
9. The combustion chamber as recited in claim 1 , wherein the at least one through-opening is disposed in the support element at a bottom of the gap.
10. The combustion system as recited in claim 8 , wherein the at least one through-opening is disposed in the support element at a bottom of the gap.
