The fins used on the boiler superheater tubes are an essential structural component designed to amplify heat transfer efficiency. They primarily function to extend the heating area, thereby boosting the heat transfer rate significantly. Crafted from high-quality materials such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit superior high-temperature and corrosion resistance, ensuring long-lasting, stable operation. During the fin manufacturing process, careful consideration is given to cost-effectiveness and advanced processing technologies to achieve optimal performance.
Utilizing fins effectively addresses the issue of scaling on the inner walls of boiler superheater tubes. This scaling can diminish the heat transfer area of the tube wall, negatively impacting heat transfer efficiency. By incorporating fins, the operational costs of boilers are significantly reduced, as they contribute to decreased fuel consumption and enhanced overall boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: The addition of fins significantly augments the surface area on the exterior of the tube. This allows the smoke passing through the fins to transfer heat more efficiently to the medium inside the tube, typically steam, dramatically enhancing the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: An expanded heating area correlates directly with a higher heat transfer coefficient. This ensures that the heat transfer process is faster and more effective, which is crucial for maintaining optimal boiler efficiency and precise steam temperature control.
3. Diverse structural forms: The fins boast versatile structural forms. They can be spiral-shaped, continuously enveloping the steel pipe with high-frequency welding for robust attachment, ensuring they remain intact. Alternatively, they can feature a separate circular sheet shape, which, while subjected to a singular force, can minimize dust accumulation and eliminate dead corners in various applications.
4. Membrane wall application: In structures utilizing water-cooled walls, employing finned tubes creates a 'membrane wall'. This configuration not only expands the heating surface but also enhances sealing performance, reduces boiler air leakage, and significantly boosts overall thermal efficiency.
6. Welding strength and stability: Premium quality finned tubes must undergo rigorous welding strength evaluations, such as pull-out force tests exceeding 200MPa. These tests ensure the welding parts' stability and reliability, guaranteeing enduring performance.
7. Specific design applications: For instance, double H-shaped finned tubes, with their innovative design, deliver greater heating surfaces and superior heat transfer efficiency compared to conventional finned tubes. They are ideal for power plant boilers, industrial boilers, and flue gas waste heat recovery systems, offering unmatched performance in demanding applications.
