The invention relates to the technical field of pipeline ash removal, and discloses an exhaust gas heat exchanger pipeline ash removal method and device.The exhaust gas heat exchanger pipeline ash removal method comprises the steps that an ash removal device is placed in a pipeline through which exhaust gas passes, and the cleaning part of the ash removal device abuts against the inner wall of the pipeline; when exhaust gas is transported in the pipeline, the cleaning part in the ash cleaning device is pushed to move in the pipeline, the cleaning part can be pushed to move relative to the inner wall of the pipeline, and ash on the inner wall of the pipeline is scraped; and the scraped ash is discharged through an ash discharging part in the ash cleaning device. According to the exhaust gas heat exchanger pipeline ash removal method and device, the ash removal device is pushed to move in the pipeline by utilizing the power of transporting air in the pipeline, chance cakes on the inner pipe wall of the pipeline
