...Abstract Abstract An alloy IN-690 (N06690) incinerator liner approximately 0.8 mm (0.031 in.) thick failed after only 250 h of service burning solid waste. Investigation supported the conclusion that the root cause of the failure was overfiring during startup and sulfidation of the nickel-base...

... corroded away, leaving a weak, porous residual structure. The brazing alloy was of type CP 1 as covered by BS 1845. Header and tube materials were basically copper-nickel alloys for which the use of a phosphorus bearing brazing alloy is not recommended owing to the possibility of forming the brittle...
