Thermocouple protection systems for longer service life in slagging gasifier environments
To ensure reliable and efficient operation, gasifier operators would like to be able to continuously monitor system temperature. In many slagging gasifiers, temperature measurement is accomplished by several thermocouples embedded at various locations in the gasifier wall. Unfortunately, these thermocouple devices are very susceptible to early failure, either as the result of mechanical stresses or exposure to the harsh slagging environment, making long-term continuous temperature monitoring difficult. At the Albany Research Center, we are developing strategies to improve the ceramic protection assembly that is used to shield the thermocouple wires from direct exposure to the gasifier atmosphere. In this talk we will describe this multi-component ceramic protection system and present test results, which indicate that, the protection system should provide longer device service life in slagging gasifier environments.
