The internal circulation of flue gas and the full recovery of annular cooling flue gas applied in the No.3 sintering system of Angang are the first two circulating systems in China.The circulating quantity and parameters of sintering flue gas have a direct impact on the quality of sinter minerals,while the circulating quantity and parameters of annular cooling machine have a direct impact on the cooling effect of sinter.There is no ready experience for the operation of the two systems and the main sintering system.After research,the technical personnel of Angang have realized the double benefits of reducing pollutant emission and improving production,on the basis of internal circu-lation of sintering flue gas and full recovery of ring cooling flue gas,ensuring the trend of sintering process and the stability of sintering mineral qualityt.
