Abstract
A turbomachine with at least one combustion chamber and at least one turbine which lies downstream of it. The turbine has at least one support element and a lining element connected to the support element and formed as a heat shield. A gap sealed by means of a seal, is formed between the at least one combustion chamber and the turbine, an exchangeable insert is arranged in the gap on the end face on the support element and protects at least the support element against hot gases which penetrate into the gap, and against oxidation which is associated with it.

A turbomachine comprising:
- at least one combustion chamber;
- at least one turbine lying downstream to the combustion chamber, a gap disposed between the at least one combustion chamber and the at least one turbine;
- a support element having an end face facing the gap;
- a lining element connected to the support element and forming a heat shield over the support element;
- an exchangeable insert disposed in the gap, the exchangeable insert covering the end face of the support element so as to be exposed to hot gases and the exchangeable insert abutting the lining element so as to protect the support element against the hot gases;
- a seal retained on the exchangeable insert and configured to seal the gap;
- and,
- wherein the exchangeable insert is more oxidation-resistant than the support element.
