The fins utilized on the boiler superheater tubes serve as a pivotal structural component engineered to augment heat transfer efficiency. These fins are primarily designed to amplify the heating area, thereby optimizing the heat transfer rate. Crafted from robust metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins exhibit exceptional high-temperature and corrosion resistance, ensuring stable, long-lasting operation. During the manufacturing process, careful consideration is given to cost-effectiveness and processing technology to ensure optimal performance.
Fins proficiently address the challenge of scaling on the inner walls of boiler superheater tubes. Scaling can significantly diminish the heat transfer area of the tube wall, leading to reduced heat transfer efficiency. By incorporating fins, the operational costs of boilers are lowered as they effectively decrease fuel consumption and enhance boiler performance.
Functional characteristics of boiler tube fins:
1. Increase heating area: Fins expand the surface area externally on the tube, enabling the smoke flowing between them to transfer heat more efficiently to the medium inside (typically steam). This innovative design substantially magnifies the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: A more extensive heating area directly correlates with an elevated heat transfer coefficient, which translates to a more swift and efficacious heat transfer process. This enhancement is vital for ensuring high boiler efficiency and precise steam temperature regulation.
3. Diverse structural forms: Fins may adopt diverse forms such as spiral shapes that continuously envelop the steel pipe, secured by high-frequency welding for integrity and durability. Alternatively, they can be separate circular sheets that, despite being subjected to singular forces, may mitigate issues like dust accumulation and dead corners in specific applications.
4. Membrane wall application: In water-cooled wall structures, the employment of finned tubes is recognized as a 'membrane wall'. It significantly expands the heating surface, while simultaneously enhancing sealing performance, reducing boiler air leakage, and elevating overall thermal efficiency.
6. Welding strength and stability: Superior quality finned tubes are subject to rigorous welding strength evaluations, including pull-out force tests requiring values greater than 200MPa, to guarantee the welding part's stability and reliability.
7. Specific design applications: For instance, double H-shaped finned tubes, owing to their distinctive design, offer superior heating surfaces and enhanced heat transfer efficiency over ordinary finned tubes in power plant boilers, industrial boilers, and systems for recovering waste heat from flue gases.
