The transformation of the low nitrogen burner of Unipetrochemical has achieved remarkable results

China Petroleum Network news (reporter Li Zhiqiang) as of February 1, Dushanzi petrochemical ethylene 2 joint no. 7 cracking furnace a successful feeding 28 days, marking no. 7 furnace successfully completed the transformation and maintenance of low nitrogen burner, has completed all 7 old area, 2 new area low nitrogen burner transformation.

It is understood that the transformation of the low nitrogen burner of the cracking furnace is to meet the requirements of the nitrogen oxide concentration in the flue gas of the heating furnace less than 100 mg per cubic meter in order to meet the emission standards of pollutants in the petrochemical industry (GB31571-2015). At present, the modified low nitrogen burner can run normally, the combustion flame is in good condition, the surface temperature of the furnace tube and the temperature difference between upper and lower is within the normal range, there is no influence on the operation cycle of the cracking furnace, nitrogen oxide and carbon monoxide in the flue gas meet the national standard emission requirements.

Du Petrochemical strengthened communication with ZEECO, strictly implemented the technical agreement standards, completed THE CFD and combustion test report on time to ensure the successful completion of the transformation, and further studied the problem of coke burning and flue gas standards during the heating and cooling period on the basis of the previous work. The material purchasing department should accelerate the timely arrival of ZEECO's low nitrogen burner and strictly control the supply quality.
