Program to discover materials suitable for service under hostile conditions obtaining in equipment for the gasification of coal and other solid fuels. Annual progress report, January 1, 1976--December 31, 1976
- ed.
This Annual Report describes, in general, the progress during the year 1976 on a program under the direction of The Metal Properties Council, Inc. designed to screen materials for use in such plants with respect to the various unique corrosive environments obtaining therein; and, finally to provide useful corrosion data as well as reliable information on other properties needed for the design, construction, and operation of such plants. Corrosion tests were conducted in the gasifier gas composition at 1800/sup 0/F and 1000 psi; results are reported. Evaluation of metals and refractories continued in the HYGAS, Consol and Synthane pilot plants. A significant amount of additional corrosion data was obtained and analyzed during the current year. Currently, the statistical test series is being continued to explore the effects of temperature, pressure, and ammonia concentration on corrosion rate. Design, fabrication, and procurement of two high-pressure reactor vessels, a dual-head high-pressure, high-temperature recirculating gas compressor, and other components, were completed. The results of the first ten atmospheric pressure tests have been critically analyzed revealing that, under certain test conditions, the slagging erosion effect can virtually destroy many high-temperature alloys in 50 hr. The results also showed that the aluminide coatings do afford significant protection in these 50-hr tests, but may be subject to an incubation time effect that can only be verified by conducting longer-term tests.
