【Discussion】High-temperature thermocouples on the reaction furnace
Thread Content
Does everyone’s factory reactor have this thing installed? What’s the situation if it’s being used currently? Is the measured temperature accurate? Is the ceramic sleeve prone to damage? Everyone is welcome to join the discussion
There is usually wind protection, otherwise it can be easily damaged by fire； An infrared thermometer can be used.
Thermocouples and infrared are usually used together. How to extend the service life of high-temperature thermocouples is a long-standing problem in sulfur recovery units. Generally, thermocouples need to be cooled with nitrogen; otherwise, they are prone to damage.
This issue is indeed quite difficult; please refer to my request post <<How to address the short lifespan of thermocouples in the acidic gas combustion furnace of sulfur recovery units>> http://bbs.hcbbs.com/thread-400958-1-1.html
I took a close look at that post. The damage to the thermocouple is mainly due to damage to the ceramic sleeve; wouldn’t this cause the outer wall of the reaction furnace to overheat? Then the furnace must be shut down
