Increase the main air flow, reduce the amount of coke formed, and add a large quantity of CO as an oxidizing agent.
If it is flue gas from a heating furnace, it is necessary to reduce the ventilation volume, decrease the opening degree of the dampers and flue baffles, or adjust the fuel amount to ensure the furnace’s thermal efficiency
3# ai444099439 has a high CO content; it’s probably due to incomplete fuel combustion, meaning there is less oxygen present!
Incomplete combustion is likely due to an insufficient main air flow. Be careful to add some combustion aid first when increasing the main air volume, in order to prevent secondary combustion and afterburning.
Sometimes, there is air leakage in the heating furnace body; this phenomenon often occurs when the flue dampers or air valves are manually reduced in size to ensure that the oxygen content in the flue gases remains within the specified limits. Another possibility is that insufficient air supply to individual burners could also cause this issue. Oxygen content must be sampled and analyzed separately from the radiation zone and the convection zone, and the combustion condition of the burner must be examined; only through a comprehensive analysis can the cause of the excessive carbon monoxide levels be determined.
The high CO content in the flue gas is likely due to issues with the operations at the reaction station. First, it is necessary to prevent CO from remaining unburned; secondly, the operating procedures need to be improved by gradually increasing the air supply volume in order to enhance the burning effect. The burning temperature should also be kept around 690°C as much as possible
