The fins engineered for the boiler's superheater tubes serve as a crucial structural attribute, significantly boosting heat transfer efficiency. Primarily, they are designed to expand the heating area, thereby magnifying the heat transfer rate manifold. Crafted from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast exceptional high-temperature and corrosion resistance, ensuring consistent, long-lasting operation. Both cost-effectiveness and advanced processing technology are integral considerations in the manufacturing of these fins to optimize performance.
Employing fins provides an innovative solution to the scaling issue on the inner walls of boiler superheater tubes. Scaling diminishes the heat transfer area of the tube walls, thus impairing efficiency. Fins not only rectify this by enhancing heat transfer but also lower boiler operational costs through reduced fuel consumption and heightened boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: The fins adeptly augment the tube's external surface area, enabling the smoke traversing between them to transmit heat more effectively to the steam inside the tube. This ingenious design significantly amplifies the heat transfer capability per unit volume.
2. Improve heat transfer efficiency: An enlarged heating area correlates directly with an elevated heat transfer coefficient, facilitating a swift and efficient heat transfer process. This is pivotal for maintaining optimal boiler performance and precise steam temperature regulation.
3. Diverse structural forms: Fins may take on a spiral configuration, encircling the steel pipe with a high-frequency welded attachment for utmost firmness. Alternatively, they can be standalone circular sheets, minimizing dust accumulation and dead zones in specific scenarios.
4. Membrane wall application: When finned tubes are implemented within water-cooled wall structures, it's termed as a 'membrane wall'. This not only expands the heating surface area but also offers superior sealing capabilities, reduces air leakages in boilers, and elevates overall thermal efficiency.
6. Welding strength and stability: Premium finned tubes must undergo rigorous welding strength assessments, including pull-out force tests exceeding 200MPa, to validate the durability and dependability of the welded joints.
7. Specific design applications: Double H-shaped finned tubes, thanks to their unique configuration, deliver substantially greater heating surfaces and superior heat transfer efficiency compared to standard finned tubes. These are particularly advantageous in power plant boilers, industrial boilers, and systems designed for flue gas waste heat recovery.
