A 2.25 sq ft (0.21 sq m) atmospheric fluidized bed combustor (AFBC), using Illinois No. 6 coal and Quincy limestone is being used to test the in-bed corrosion resistance of selected austenitic alloys with a maximum metal temperature of 870 C (1600 F). This paper describes the combustor test facility, test parameters, materials selection and summarizes the results after 1500 hr of testing.
