The furnace temperature of the sulfur-burning furnace of the sulfur recovery unit is an important parameter to ensure the overall Claus reaction, and it is of great significance to accurately evaluate the extent of the reaction. At present, the temperature measurement of sulfur recovery furnace is a recognized technical problem in the industry, mainly affected by high temperature, high temperature H2 S corrosion and thermal shock. Therefore, the material of the thermocouple protection sleeve is difficult to select. Through the analysis of the high temperature thermocouple modification process of the sulfur recovery furnace in the sulfur recovery unit of this department, the paper summarizes the transformation plan to extend the service life of the high temperature thermocouple of the device.
