Abstract:

The new national standard “Emission standard of pollutants for coking chemical industry”  regulates the requirement for control of NOx emission from chimney of coke oven battery.The technical measures on design of heating system of coke oven battery and treatment of oven flue gas after it is discharged from the battery for  control of NOx emission are expounded in this paper.The author also makes brief description of technology on denitrification of flue gas by using SCR process and suggests that in order to meet the requirement of the national standard for control of NOx emission from chimney of coke oven battery located in the “special region”, flue gas discharged from the coke oven battery should be further treated by using SCR denitrification technology with learning experience of Tokyo Gas gained from test of pilot plant and engineering.
