The fins incorporated into the boiler superheater tubes serve as pivotal structural enhancements that significantly boost heat transfer efficiency. Primarily, their role is to broaden the heating surface, thus amplifying the rate at which heat is exchanged. Constructed from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit exceptional resistance to high temperatures and corrosion, ensuring prolonged and stable operation. During their production, both cost-effectiveness and advanced processing technologies are meticulously considered.
Fins effectively address the scaling issues on the inner walls of boiler superheater tubes. Scaling diminishes the heat transfer area, thereby impeding efficiency. By implementing fins, this challenge is mitigated, enhancing the operational efficiency of boilers and reducing fuel consumption, thus significantly optimizing overall boiler performance.
Functional Characteristics of Boiler Tube Fins:
1. Expand Heating Area: The fins augment the surface area on the tube's exterior, thus enabling smoke traversing between them to more efficiently convey heat to the tube's internal medium, typically steam. This innovative design substantially boosts the heat transfer capability per unit volume.
2. Amplify Heat Transfer Efficiency: An expanded heating area correlates directly with an elevated heat transfer coefficient, indicating a swifter and more effective heat transfer process. This is crucial for maintaining boiler efficiency and precise steam temperature regulation.
3. Diverse Structural Configurations: Fins come in spiral shapes, continuously encompassing the steel pipe and secured through high-frequency welding, ensuring firmness and resistance to detachment. Alternatively, circular sheet-shaped fins, though subject to singular forces, may alleviate issues of dust accumulation and dead corners in certain applications.
4. Membrane Wall Application: In water-cooled wall structures, the use of finned tubes is termed a 'membrane wall'. This not only expands the heating surface but also enhances sealing performance, minimizes boiler air leakage, and bolsters overall thermal efficiency.
6. Welding Strength and Stability: High-quality finned tubes must undergo rigorous welding strength assessments, such as pull-out force tests exceeding 200MPa, to guarantee the stability and reliability of the welded segments.
7. Specialized Design Applications: For instance, double H-shaped finned tubes, through their distinctive design, deliver superior heating surfaces and heightened heat transfer efficiency compared to standard finned tubes in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
