Abstract： In the operation of a sintering flue gas treatment project， the outlet flue of the main extraction fan and the condenser flue appear different degrees of intermittent vibration， and the causes of these vibrations were complex. Based on the investigation and analysis results of the system operation and smoke flow field， the system equipment and production process were rectified to eliminate the vibration condition and ensure the normal operation of the sintering flue gas treatment system. The sintering yield has reached the design value， which provides reference for similar projects.
