The main components of coke oven flue gas were SO 2 , NO X etc. SO 2 and NO X were not only harmful to human health, but also seriously polluted the environment. The stricter “Standard for Discharge of Pollutants from coking chemical industry” was introduced. An integration settlement scheme of flue gas desulfurization, denitration and waste heat recovery was put forward. The proprietary core technologies, such as denitration, COG desulfurization and radial heat pipe boiler were researched. The integration settlement scheme can solve the problems of polluting the environment and waste heat without recovery, which had not only significant economic benefits, but also huge social benefits.
