Microbiologically Influenced Corrosion Investigations in Electric Power Generating Stations

Abstract

Abstract The results of surveys of microbiologically influenced corrosion (MIC) at electric power generating stations and the authors' on-site investigations have shown that MIC can be a serious problem in these facilities. Almost all systems and types of alloys were affected. The data obtained suggest that acid-producing bacteria play a significant role in MIC of carbon steel and perhaps other alloys. Two case histories of MIC in electric generating stations are presented to illustrate the MIC investigation process. The practical and theoretical aspects of MIC are discussed with a view towards minimizing the impact this problem has on the electric power generating industry.
