Chemical and Physical Stability of Refractories for Use in Coal Gasification. Sixteenth Quarterly Progress Report, February 1, 1980-April 30, 1980

摘要

Experiments on the corrosion resistance and thermal expansion of refractories for coal gasification plants are reported. The properties of a given castable were basically similar after exposure, regardless of whether the specimens had been immersed in liquid or in contact with saturated vapor. The thermal expansion of several refractories over the temperature range of 20 exp 0 C to 950 exp 0 C, and exposed to the DOE atmosphere of containing 1 vol % H sub 2 S at 1000 psi, is reported. Some samples were cycled from 465 exp 0 C to 1000 exp 0 C. (ERA citation 05:025139)
