Abstract
The present invention relates to a combustion chamber heat-shielding element of a gas-turbine, having a bolt for mounting the combustion chamber heat-shielding element on a combustion chamber wall or a combustion chamber head, where the combustion chamber heat-shielding element is designed substantially plate-like and where on one side at least one bolt, which is designed as a separate component, is anchored on it by means of a bonded connection.
Claims8
A combustion chamber heat-shielding arrangement of a gas-turbine, comprising:
- a combustion chamber heat-shielding element having a plate shape,
- a bolt for mounting the combustion chamber heat-shielding element on a combustion chamber wall or a combustion chamber head, the bolt configured as a separate component from the combustion chamber heat-shielding element, the bolt having a first end having a non-cylindrical contoured base for anchoring to the combustion chamber heat-shielding element,
- a receptacle provided on the combustion chamber heat-shielding element, the receptacle including a non-cylindrical recess shaped for receiving the non-cylindrical contoured base of the first end of the bolt in a form fitting and rotational preventing locking manner,
- an adhesive bonded connection connecting the first end of the bolt to the non-cylindrical recess, the adhesive bonded connection consisting of the first end of the bolt, the non-cylindrical recess and an adhesive positioned between and connecting the first end of the bolt to the non-cylindrical recess, wherein the adhesive consists of a high-temperature resistant metal adhesive resistant to temperatures of at least 1000° C.,
- wherein the receptacle includes effusion cooling holes.
