Nitrogen oxide emissions in flue gas
Thread Content
After the catalytic device is turned on, the NOx levels in the flue gas exceed the allowed limits; how should adjustments be made in operation?
Strictly follow the operating procedures; in case of any abnormalities, inform the superior authorities promptly. If it is to be resolved through technical discussions, this requires coordination with the design agency. If a solution is to be found through control measures, it is best to first establish revised operating procedures. This is related to the equipment; whether it is connected to the original design remains to be determined.
One is to add denitration facilities at the back end, and the other is to use denitration agents
