What issues should be considered during the heating-up and commissioning of sulfur recovery units?

Control the temperature at each stage, and manage the rate of temperature increase properly, especially during the low-temperature phase. 2. Check whether the ignition gun provided by the manufacturer has a low-temperature drying function; if not, an electric furnace can be placed inside the sulfur production furnace to carry out drying at low temperatures. 3. When the temperature is ≤500℃ in the early stage of furnace drying, a low-temperature thermocouple should be used; later on, a high-temperature infrared thermocouple should be used instead. 4. Raise the temperature using the heating curve provided by the manufacturer, plot the actual oven heating curve, and conduct a comparison. 5. During the furnace drying stage, pay attention to air distribution and peroxide combustion to prevent carbon deposition. 6. Pay attention to protecting the thermocouples and various viewing ports, and adjust the flow rate of cold nitrogen accordingly based on the furnace temperature. If there is a high-temperature mixing valve, pay attention to protecting it as well. 7. During furnace drying, strengthen on-site inspections to check for any leaks or abnormal conditions.
