IMPROVED MARINE BOILER RELIABILITY, PHASE II. VOLUME I. SUPERHEATER CORROSION RATES. 950 DEG F OUTLET STEAM TEMPERATURE
The report presents the corrosion potential of commercially utilized superheater materials in a modern marine boiler under shipboard operating conditions. A comparison of wastage potential of several superheater materials over a selected temperature range was accomplished by the use of controlled temperature probes. Effect of exposure duration was determined by comparison of two identical probes removed from service at different time intervals. Several coatings were evaluated in this marine application. Physical measurements and chemical analysis of deposits and metallurgical techniques were used to develop the results generated by these probes. This information is intended for use in establishing safe operating temperatures for selected materials of fabrication.
