The first portion of a 1000 hour exposure test of potential gas turbine and boiler tube materials suitable for use in Pressurized Fluidized Bed Coal Combustion (PFBC) was successfully completed. A 250 hour test was carried out in the Exxon PFBC Miniplant under realistic test conditions. The run was interrupted for one six hour period. Flue gas temperatures downstream of the combustor were maintained at 1550/sup 0/F or higher. Gas turbine and boiler tube specimens showed no obvious signs of damage after the 250 hour test. The gas turbine specimens showed some signs of deposition, but the deposits were easily removed by brushing.
