Failure Analysis of a Heavy Duty Gas Turbine Blad
This paper reports the failure analysis of a blade in a heavy duty land-base gas turbine. The power plant is located near the coastal area and also in vicinity of deserts of Iran, as a consequence, the airborne pollutants entering with the inlet air into the turbine. Most of the blades from one sta...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | This paper reports the failure analysis of a blade in a
heavy duty land-base gas turbine. The power plant is located near the coastal area and also in vicinity of deserts of Iran, as a consequence, the airborne pollutants entering with the inlet air into the turbine. Most of the blades from one stage of this gas turbine had deteriorated after nearly 25,000 EOH of service. One of these blades was broken through
the airfoil from the section located at almost two-third of span. The predicted service life was 100,000 h. The turbine runs with gasoline and filtered air. The broken blade was received for study. The objective of the present work is to determine the root cause of the blade failure. |
