High O2 content in sulfur chimneys

Environmental regulations are becoming increasingly strict; monitoring devices have been installed on sulfur chimneys, and the O2 level in these chimneys is converted into an SO2 value based on a certain ratio. In other words, the higher the O2 content, the higher the equivalent SO2 level. Our O2 content is generally around 6%–7%. How can we reduce the O2 content in the chimney? Please share your ideas; there will be prizes for the best suggestions.

To reduce sulfur dioxide levels, you can try to lower the wind speed, but do not reduce the gas supply; instead, increase the amount of gas used as long as the furnace temperature remains satisfactory
Reduce the air volume, or appropriately increase the concentration of acidic gases
The key lies in the burner design – whether it can ensure sufficient contact between the fuel gas and air for complete combustion. Additionally, attention should also be paid to the furnace design – is there any flow deviation?
It has little to do with the sulfur production furnace; the main issue is improper air supply in the incinerator
