The fins employed on boiler superheater tubes are ingeniously crafted structural components that significantly enhance heat transfer efficiency. Primarily, they are utilized to expand the heating area, thereby boosting the heat transfer rate. These fins are meticulously constructed from top-tier metals including 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, bestowing exceptional high-temperature and corrosion resistance. This ensures long-lasting and stable operation. During the manufacturing process, we diligently consider both cost-effectiveness and the rationality of processing technology.
Incorporating fins effectively addresses the common issue of scaling on the inner walls of boiler superheater tubes. Scaling reduces the heat transfer area, consequently impairing heat transfer efficiency. By using fins, the heat transfer area is maintained, thus enhancing efficiency. Moreover, fins contribute to reduced operating costs, as they lower fuel consumption and elevate overall boiler efficiency.
Functional characteristics of boiler tube fins:
1. Expand Heating Area: Fins substantially increase the surface area around the tube, enabling smoke passing between the fins to transfer heat more effectively to the interior medium, typically steam. This innovative design markedly amplifies the heat transfer capacity per unit volume.
2. Enhance Heat Transfer Efficiency: A more extensive heating area correlates to a higher heat transfer coefficient, facilitating a quicker and more effective heat transfer process. This is vital for maintaining optimal boiler efficiency and precise steam temperature control.
3. Versatile Structural Forms: Fins are available in spiral forms, tightly encircling the steel pipe and secured by high-frequency welding for durability. Alternatively, they can be in separate circular sheet forms, each designed to minimize dust accumulation and address dead corners in certain scenarios.
4. Membrane Wall Application: In water-cooled wall structures, utilizing finned tubes results in a configuration known as a 'membrane wall.' This not only enhances the heating surface but also provides superior sealing, minimizes boiler air leakage, and elevates the overall thermal efficiency.
6. Superior Welding Strength and Stability: Premium quality finned tubes undergo rigorous welding strength assessments, including pull-out force tests exceeding 200MPa. This guarantees the welding part's unwavering stability and reliability.
7. Tailored Design Applications: For instance, double H-shaped finned tubes, owing to their distinctive design, offer superior heating surfaces and heat transfer efficiency compared to conventional finned tubes. They are particularly advantageous in power plant boilers, industrial boilers, and systems for flue gas waste heat recovery.
