Failure Analysis of Outer Swirls in the Fuel Nozzle

Abstract:

Failure analysis of 4 swirls in the fuel nozzle of a gas turbine was made by macroscopic and microscopic examination, and verified test were conducted. The result showed that the swirls in the fuel nozzle subjected thermal fatigue and failed in different manner for different reasons.
