    Abstract

    Corrosion tests of candidate materials for heat exchangers using liquid fluidized bed technology were conducted at the U.S. Department of Energy's geothermal wells at Raft River, Idaho, and at the Geothermal Components Test Facility (GCTF) in East Mesa, Calif. These investigations deal with moderate temperature ranges of 135 to 163°C for electrical generation and nonelectrical applications. The corrosion, erosion, and scale buildup were evaluated. The average penetration of Type 1025 carbon steel was 314 μm/year. Hastelloy alloys G and C276, stainless steels Type 304L, Type 316, Type 347, and Nitronic 50 had average penetrations of less than 2 μm/year.
