Understanding Corrosion in Oxy-Fired Systems

Performer: Oak Ridge National Laboratory

Project No: FWP-FEAA106


Assembly of an in-situ high temperature materials creep testing machine was completed, and experiments in a steam atmosphere were started.

Oxidations tests on a wide range of ferritic, stainless steel and nickel alloys have been completed with test durations up to 4000 hours. Test conditions were at 550 or 600 °C, and included exposure of the samples to 100 % steam, 50 % / 50 % mixtures of steam and CO2, or air/water vapor/CO2 plus sulfur dioxide. Some tests also contained simulated coal ash.
