Pollutants discharged from a coke oven chimney mainly comprise SO2, NOx, smoke dust and the like, are continuously discharged from organized overhead points, and are one of main pollution sources for polluting atmosphere. When the fuel gas is burnt in the vertical flue of the coke oven, nitrogen oxides NOx are generated, and the generation mechanism of the nitrogen oxides NOx is divided into a temperature thermal type, a hydrocarbon fuel rapid type and an oxygen-containing component fuel type. When the air excess coefficient alpha is 1.1 and the air is preheated to 1100 ℃, the theoretical combustion temperature of the coke oven gas is 2350 ℃ and the theoretical combustion temperature of the blast furnace gas is 2150 ℃. It is generally believed that the actual combustion temperature is below this value and is between the theoretical combustion temperature and the measured temperature of the duct brickwork.
