[0002] A boiler is an energy conversion device that generates heat by burning fuel and conducts the heat through boiler tubes to the location where it is needed. Therefore, boilers are widely used in industrial production and daily life.

[0003] Patent CN221923421 U discloses a boiler heating surface tube bank fixing device, including comb-shaped plates and bolts. The comb-shaped plates consist of two symmetrically arranged plates, each with a continuously wavy arc-shaped groove along its extension direction. Each comb-shaped plate has connecting holes at its left and right ends for fixing. The two comb-shaped plates form a detachable connection structure through bolts and connecting holes. Each comb-shaped plate also has continuously wavy protrusions at its front and rear ends along its edge extension direction. The overall structure of this device adopts a component-based disassembly method, making installation and disassembly convenient. After fixing, this patented device is unaffected by the dynamic field disturbance of flue gas during high-temperature flue gas operation, preventing warping and deformation. During boiler operation, this device can firmly fix the tube bank, thus avoiding misalignment, disorder, and deformation, thereby reducing tube bank wear rate and the incidence of tube bank leakage and burst accidents.
