Discussion on regenerating acidic gas to the middle section of the sulfur production furnace
Thread Content

Releasing acidic gas into the middle of the sulfur production furnace reduced the amount of acidic gas in the front section; with the air flow remaining unchanged, superoxide combustion occurred, which naturally led to an increase in temperature. As for the control ratio, it depends on the temperature you want to control; raising the temperature is mainly to reach the temperature required for ammonia combustion
The middle feed of the acidic gas consists of ammonia-free acidic gas, while the front part contains ammonia-containing acidic gas. The middle feed is used to ensure that the sulfur production furnace has a high enough temperature to allow complete combustion of ammonia; the minimum temperature required for complete combustion of ammonia is 1250 degrees.

In the gases after combustion, the H2S/SO2 ratio is 2:1, at which point the concentration of elemental sulfur is highest
It is best not to let the amount of acid gas diverted exceed 1/3 of the total acid gas volume
When the temperature in the sulfur production furnace is too low to support ammonia combustion, a portion of the acidic gas is diverted to the middle part of the furnace for secondary combustion, thereby increasing the temperature downstream of the furnace. The amount of acidic gas entering the middle section should be at most 2/3 of the total amount.
I still haven’t figured out this problem; I’ve been studying it*
I think 2/3 as mentioned on the 7th floor is an excessive amount; it could lead to too much oxygen in the front part of the furnace, ultimately causing overheating.
I agree with this; the specific ratio should be determined by the furnace temperature, as long as it is possible to raise the furnace temperature to the level required for ammonia combustion.
The central amount should be 1/4 to 1/3 of the total amount of ammonia and clean acid gas.
