The fins employed on the boiler superheater tubes serve as a vital structural component designed to significantly boost heat transfer efficiency. Primarily utilized to expand the heating area, these fins heightenedly enhance the heat transfer rate. Crafted from high-performance metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, they exhibit remarkable high-temperature and corrosion resistance, ensuring stable, long-lasting operation. During manufacturing, both cost-effectiveness and processing technology are meticulously considered.
The integration of fins ingeniously resolves the issue of scaling on the inner wall of boiler superheater tubes. Scaling can diminish the heat transfer area of the tube wall, adversely affecting efficiency. Fins not only counteract this but also lower the operational costs of boilers by reducing fuel consumption and enhancing boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: Fins amplify the external surface area of the tube, enabling the smoke traversing between fins to transfer heat more effectively to the internal medium (commonly steam). This innovative design significantly elevates the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: An expanded heating area correlates directly with a higher heat transfer coefficient, ensuring a faster and more effective heat transfer process. This enhancement is vital for maximizing boiler efficiency and controlling steam temperature.
3. Diverse structural forms: Fins can be spirally shaped, enveloping the steel pipe continuously, and are secured through high-frequency welding for a robust and secure fit. Alternatively, they can be individual circular sheets, which may reduce dust accumulation and eliminate dead corners in various applications.
4. Membrane wall application: In water-cooled wall structures, employing finned tubes results in a 'membrane wall' configuration. This not only amplifies the heating surface but also enhances sealing performance, reduces boiler air leakage, and boosts overall thermal efficiency.
6. Welding strength and stability: Top-tier finned tubes undergo rigorous welding strength tests, including pull-out force tests surpassing 200MPa, ensuring the welding part's enduring stability and reliability.
7. Specific design applications: Double H-shaped finned tubes, with their distinctive design, deliver greater heating surfaces and heightened heat transfer efficiency compared to conventional finned tubes. These are ideal for power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
