Abstract:

The limit value of SO2 emitted from coke oven chimney is defined as 50mg/Nm3 in the GB 16171-2012 “Emission standard of pollutants for coking chemical industry”.Most of coking plants can’t reach the limit value even the operation is in good condition.This paper analyzes the factors which effect the concentration of SO2 in chimney and provides with some reasonable suggestions and supplement for GB 16171—2012.
