The General Electric Company, under contract to the Department of Energy, is conducting a long-term materials test at the G.E. Malta Pressurized Fluidized-Bed Combustor (PFBC) test facility. The primary objective of the test program is to determine the corrosion resistance of candidate gas turbine vane and blade base alloys and protective coating systems in the effluent from a pressurized fluidized bed coal combustor for extended periods of time up to 10,000 hours. The rig consists of a coal/dolomite feed system, combustor, three stages of cyclone cleanup, and two material test sections. Heat is extracted by an in-bed water-cooled heat exchanger. The first low-velocity test section (LVTS) contains 180 pin specimens, 60 of which are air cooled. The second high-velocity test section (HVTS) consists of 24 airfoils arranged in 4 cascades. Results discussed here are based upon specimens exposed in the low velocity test section to hot combustion gases at temperatures of 788-816 C uncooled and 593-704 C using air cooled hollow pins. Base alloys, coatings, and claddings selected for exposure in the test are listed and discussed. 1 figure, 3 tables.
