Failure of Incoloy 800H superheater tubes in Mountain Fuel Resources Gasifier

Journal Article · · Mater. Compon. Fossil Energy Appl.; (United States)
OSTI ID:7090790
A failure analysis of the Incoloy 800H superheater tubes in the Mountain Fuel Resources Gasifier is discussed. Chemical analysis indicated that the alloy chemistry was within the specifications for Incoloy 800H and no unusual impurity levels were noted. It was found that cracks initiating in the outer surface of the superheater tubing played the predominate role in the failure.
