Abstract

The erosion of materials is recognized to be a serious problem in coal conversion plants, being responsible for approximately 21% of all component failures reported as of April 6, 1979, according to the National Bureau of Standards Failure Information Center summary report.1 The components which have been especially plagued by erosion problems are the control and let-down valves2,3 and slurry feed pumps.3
