The robust fins incorporated into the boiler superheater tubes are a pivotal structural element, meticulously crafted to elevate heat transfer efficiency. These fins primarily serve to amplify the heating area, thereby significantly enhancing the heat transfer rate. Constructed from premium metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast exceptional high-temperature and corrosion resistance, ensuring long-lasting, reliable operation. During the manufacturing process, we expertly balance cost considerations with advanced processing technologies to deliver superior performance.
The strategic implementation of fins effectively addresses the persistent issue of scaling on the inner walls of boiler superheater tubes—scaling that often diminishes the heat transfer surface and compromises efficiency. By employing fins, operational costs of boilers are notably reduced, as they enhance boiler efficiency and lower fuel consumption, making them an indispensable component for optimized performance.
Functional characteristics of boiler tube fins:
1. Increase heating area: Fins significantly boost the surface area on the tube's exterior, allowing the smoke traversing between them to transfer heat more effectively to the medium inside the tube, typically steam. This innovative design dramatically augments heat transfer capacity per unit volume, ensuring superior thermal performance.
2. Improve heat transfer efficiency: An expanded heating area directly correlates with a heightened heat transfer coefficient, leading to a rapid and efficient heat transfer process. This enhancement is crucial for maintaining peak boiler efficiency and precise steam temperature control.
3. Diverse structural forms: Fins are available in a variety of configurations, including spiral shapes that continuously encircle the steel pipe, secured by high-frequency welding for robust durability. Alternatively, they can be fabricated as separate circular sheets, which, while subject to individual forces, may mitigate issues of dust accumulation and dead zones in certain applications.
4. Membrane wall application: In water-cooled wall frameworks, utilizing finned tubes results in a 'membrane wall,' a configuration that not only magnifies the heating surface but also enhances sealing performance, curtails boiler air leakage, and boosts overall thermal efficiency.
6. Welding strength and stability: Premium-quality finned tubes undergo rigorous welding strength assessments, including pull-out force tests exceeding 200MPa, to guarantee the unwavering stability and dependability of the welded joints.
7. Specific design applications: The distinctive design of double H-shaped finned tubes offers exceptional heating surfaces and heat transfer efficiency, often surpassing traditional finned tubes in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
