Harbin Petrochemical uses new low nitrogen incinerator to complete environmental protection and emis

　　On the 20th, the operation results of 26 new low nitrogen incinerators after revamping of atmospheric and vacuum loading and matching heaters in Harbin Petrochemical Company were calibrated, which showed that the application of new technologies greatly improved the environmental management results, and more than 110 tons of NOx were reduced every year.

　　According to inquiry, nitrogen oxide is one of the sources of pollution severely limited in emission standards of pollutants from kerosene refining industry. In order to strengthen the environmental protection management, Harbin Petrochemical Company, according to the overall decision of the environmental risk management project, in this year's inspection era, changed the burner nozzles of four heating furnace incinerators, including the atmospheric and vacuum pressure reducing furnace, hydrocracking makeup and fractionation feed heater, debutanizer bottom reboiler, and replaced the original incinerator with a new low nitrogen incinerator, which was put into operation in July. The new type of low nitrogen incinerator should adopt denitrification technology, which is to slow down the burning speed, master the burning intensity, lower the temperature of the burning area, lower the partial pressure of oxygen, etc. without affecting the load of the heating furnace and the heat compliance of the incinerator, so as to control the production of nitrogen oxide during the burning process and greatly reduce the nitrogen oxide emission of the heating furnace. According to Zhang Dianyuan, a technician of the assembly, the application of the new low nitrogen incinerator should generally consider the influence of the heating furnace heat load, fuel properties, atmosphere supply, temperature, furnace height and other components.

　　At present, the nitrogen oxide content in the atmospheric furnace flue gas of Harbin Petrochemical Co., Ltd. is 40 mg / m3, and the nitrogen oxide content in the vacuum furnace flue gas is 34 mg / m3, which is far lower than the national scale limit
