The fins employed on the boiler superheater tubes serve as a critical structural component that significantly boosts heat transfer efficiency. These ingenious fins primarily function to increase the heating surface area, thereby enhancing the overall heat transfer rate. Crafted from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit excellent high-temperature and corrosion resistance, ensuring the stable and long-term operation of the system. In manufacturing these fins, careful consideration is given to the cost-effectiveness and processing technology to achieve the best balance.
Deploying fins is a highly effective solution to the scaling issue on the inner walls of boiler superheater tubes. Scaling diminishes the heat transfer area of the tube walls, subsequently lowering the heat transfer efficiency. By utilizing fins, this problem is adeptly addressed, leading to reduced operating costs for boilers by curbing fuel consumption and enhancing boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: Fins augment the surface area on the outer part of the tube, allowing smoke that flows between these fins to more efficiently transfer heat to the medium—typically steam—inside the tube. This design significantly boosts the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: A larger heating area is intrinsically linked to an elevated heat transfer coefficient. This translates into a more rapid and effective heat transfer process, which is vital for ensuring optimal boiler efficiency and precise steam temperature control.
3. Diverse structural forms: Fins offer a variety of structural configurations. They can be spiral-shaped, encircling the steel pipe continuously and secured by high-frequency welding, ensuring firmness and resistance to detachment. Alternatively, they might take the form of separate circular sheets, which, while subjected to a single force, may minimize dust accumulation and dead corners in certain applications.
4. Membrane wall application: In the context of water-cooled wall structures, the use of finned tubes is termed a 'membrane wall.' This not only enhances the heating surface but also provides superior sealing performance, mitigates boiler air leakage, and boosts overall thermal efficiency.
6. Welding strength and stability: High-quality finned tubes undergo rigorous welding strength tests, such as pull-out force tests exceeding 200MPa, to guarantee the stability and reliability of the welded sections.
7. Specific design applications: For example, double H-shaped finned tubes feature a distinctive design that offers greater heating surfaces and heat transfer efficiency compared to standard finned tubes in scenarios like power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
