ABSTRACT:
This invention pertains to an improved high temperature slag resistant thermocouple sheath for protecting thermocouples used to measure the temperature of synthesis gas, reducing gas, or fuel gas produced by the partial oxidation of ash-containing liquid hydrocarbonaceous and/or solid carbonaceous fuels. The protection thermocouple sheath is made from a continuous binary alloy consisting of about 30 to 70 wt. % of palladium and the remainder silver. It may be used over a temperature range of about 1000.degree. F. to 2400.degree. F.
