Abstract:

This paper introduces NOx discharging conditions and NOx formation mechanism，makes a conclusion for the study development of low NOx combustion technologies such as waste gas circulation combustion，air classification combustion，fuel classification combustion，high temperature air combustion，bias combustion，low NOx combustor and catalytical combustion.It points out that future study will focus on low NOx combustion of COG.It is very hopeful to realize high efficiency and low pollution combustion of COG by combining low NOx combustion technology and traditional combustion mode of coke oven battery and boiler.
