The fins utilized on boiler superheater tubes represent a crucial structural innovation engineered to significantly enhance heat transfer efficiency. These fins primarily serve to expand the heating area, thereby substantially boosting the heat transfer rate. Crafted meticulously from metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, 30CrMoA, among others, they exhibit exceptional high-temperature and corrosion resistance, ensuring steadfast, long-term operation. The manufacturing process of these fins intricately balances cost-effectiveness and advanced processing technologies.
Implementing fins on boiler superheater tubes offers an innovative solution to tackle the prevalent issue of scaling on the inner walls. Scaling detrimentally affects the heat transfer area of the tube wall, leading to diminished heat transfer efficiency. By integrating fins, operational costs of boilers are significantly lowered as they effectively curtail fuel consumption while simultaneously enhancing boiler efficiency.
Functional characteristics of boiler tube fins:
1. Increase heating area: Ingeniously designed fins substantially enlarge the surface area on the exterior of the tube, enabling the smoke passing through the fins to more efficiently convey heat to the medium inside the tube, predominantly steam. This strategic design superbly augments the heat transfer capability per unit volume.
2. Improve heat transfer efficiency: An expanded heating area correlates directly with a heightened heat transfer coefficient, ensuring a swift and effective heat transfer process, which is paramount for optimizing boiler efficiency and maintaining precise steam temperature control.
3. Diverse structural forms: Fins are available in various structural configurations, including spiral shapes that encircle the steel pipe continuously, securely fastened through high-frequency welding, ensuring durability and resistance against detachment. Alternatively, they can be constructed as separate circular sheets, which, while exposed to isolated forces, can mitigate dust accumulation and eliminate dead corners in certain applications.
4. Membrane wall application: In the realm of water-cooled wall structures, the employment of finned tubes is termed as a "membrane wall". This innovation not only expands the heating surface but also enhances sealing performance, effectively minimizing boiler air leakage and bolstering overall thermal efficiency.
6. Welding strength and stability: Top-tier finned tubes undergo rigorous welding strength assessments, including pull-out force tests surpassing 200MPa, to certify the stability and reliability of the weld joints, ensuring exceptional performance under demanding conditions.
7. Specific design applications: For instance, double H-shaped finned tubes, with their distinctive design, deliver superior heating surfaces and heightened heat transfer efficiency compared to standard finned tubes, making them ideal for utilization in power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
