In order to solve the problem, the existing solution is to add a layer of abrasion-proof tile on the outer part of the windward side of the pipeline, reinforce the pipe wall through the abrasion-proof tile, and shield the damaged pipe wall, thereby improving the heat resistance and abrasion resistance of the pipeline. Although the abrasion-proof tile can prevent abrasion caused by smoke compared with the pipe wall, the abrasion-proof tile is easy to deform under a continuous high-temperature environment, and the edge of the abrasion-proof tile is warped. In addition, the existing anti-abrasion tile is fixed by welding, namely, the positions of two ends are sleeved outside a pipeline by welding snap rings, and the two ends of the anti-abrasion tile are limited by the pipeline; this results in the wear shoe being deformed to a central location such that the wear shoe is squeezed from both sides at the edges to form a protrusion, thereby creating a leak of smoke. Therefore, the existing boiler tail flue has the problems of poor deformation resistance and easy leakage of flue gas.
