Abstract
In a horizontal type coke oven, high temperature waste gas generated in a heating flue chamber and containing nitrogen oxides is discharged into a regenerator. There are provided nozzle openings for injecting ammonia or ammonia precursor to the high temperature waste gas at a position where the temperature of the waste gas is about 750.degree.-1000.degree. C. so as to reduce the nitrogen oxides in the waste gas with the ammonia or ammonia precursor.
