A set of simulated combustion device was designed in terms of the feature of flare gas combustion in coal-chemical industry factories,aiming to identify the effects resulting from both the addition of the liquifiedd gas and burning temperature on the emission of nitrogen oxides. And the emission coefficients of the nitrogen oxides were calculated. The test results indicate that the concentration and amount of the nitrogen oxides emitted from the torch system increase with the addition of the liquifiedd gases. In addition,the proportional relation between nitrogen oxides emission and burning temperature could be drawn based on the experiment results. The nitrogen oxides emission tended to be facilitated with the increase of burning temperature. The emission coefficient of nitrogen oxides emitted from the torch system ranged from 0. 099 to 0. 185 kg per ton,its average value was 0. 139 kg per ton.
