Abstract:

In the process of cokemaking，the atmospheric pollutant discharged from coke oven chimney is referred to as the waste flue gas after COG combustion，mainly including SO2，NOx and emission，etc.，which are the major causes of environmental pollution.By analyzing the mechanism of NOx formation in the waste flue gas and adopting the technology of COG dilution，the content of NOx in the flue gas can be dramatically reduced and the generation of NOx，therefore，can be rooted out.
