CA 2451481

A wear reduction means for a fuel nozzle interface of an industrial gas turbine combustor (10) is disclosed. The wear reduction means includes a replaceable insert (47) welded into to the engagement location (45) of the fuel nozzle tip (44). The fuel nozzle tip is coated (48) with a material harder than the replaceable insert, such that any wear due to mechanical contact of the mating components is directed to the replaceable insert.

L'invention concerne une unité de réduction d'usure destinée à une zone d'interface de l'injecteur de carburant d'une chambre à combustion (10) d'une turbine à gaz industrielle. Cette unité de réduction d'usure comprend une pièce rapportée remplaçable (47) soudée dans une zone de logement (45) destinée à la buse (44) de l'injecteur de carburant. Cette buse d'injecteur de carburant est revêtue (48) d'une matière plus dure que la pièce rapportée remplaçable de façon que l'usure due à un contact mécanique des composants accouplés ne se produise que sur la pièce rapportée remplaçable.
