Our sulfur system is also used for ammonia combustion; when the furnace temperature reaches 1150 degrees, the temperature in the hydrogenation reactor exceeds 360 degrees. What should be done in such a situation? Cool down with nitrogen, or?
What is the load, and is there an excess of oxygen? Reduce the air supply; if the furnace temperature doesn’t rise, it is recommended to use natural gas or hydrogen as a supplementary fuel.
Does mixed combustion of natural gas and acidic gases have an impact on sulfur?
It’s best to keep ammonia at its lowest level and raise the furnace temperature to 1300
If the hydrogenation reactor overheats, it can be determined that the airflow ahead is too high. Another point is whether the furnace temperature of 1150°C is accurate; it’s possible that the temperature at the measurement point is low while the actual temperature inside the furnace is higher. Here, the furnace temperature for ammonia combustion is also below 1100°C, and it has been in operation for 5 years now with no problems.
If the air supply to the sulfur production furnace is too high, it is certain that there will be an excess of sulfur dioxide in the process gas. First, check whether there is any change in the temperature rise of the sulfur production converter
Consider burning hydrogen alongside to raise the temperature; burning natural gas may cause carbon buildup
Black sulfur is basically caused by insufficient air supply; their obvious symptom is instead excessive air supply!
