Long term materials test program. Quarterly report, January-March 1982
Approximately 500 hours of corrosion validation testing have now been completed under the Long Term Materials Test. The severe corrosion on the material test specimens in the low velocity test section and formation of hard deposits in the high velocity test section during the first 250-hour test has been attributed to the high bed operating temperatures, 1800 to 1900/sup 0/F peak temperatures, and the high potassium level in the dolomite. Recently, over 250-hours of operation at peak bed temperatures less than 1700/sup 0/F, with both the high potassium dolomite (105 hours) and a dolomite of lower potassium content (153 hours), have shown that in these short exposures corrosion rates were minimal for most materials and plugging of the high velocity test section was not a problem. Further, these 250 test hours were performed in runs of 105, 82 and 71 hours without interruption demonstrating the capability for long periods of sustained operations. The in-bed heat exchanger erosion problem also appears to be solved. The single helix coil has operated for over 400 hours with no indication of erosion.
