Abstract：

The high temperature thermocouple is an important instrument for monitoring the temperature of the Kraus furnace chamber. However， the diversity， complexity and uncertainty of the feed gas of Kraus furnace bring great challenges to the long-term effective operation of the high temperature thermocouple of the furnace. The reasons for failure of high temperature thermocouple in Klaus furnace are analyzed， and the optimization measures are put forward to solve the problem that the high temperature thermocouple in Klaus furnace cannot run effectively for long.
