The innovative and robust fins employed on boiler superheater tubes are crucial structural components that significantly enhance heat transfer efficiency. They primarily serve to expand the heating area, thereby amplifying the heat transfer rate. Crafted from high-grade metals such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, 30CrMoA, these fins boast exceptional high-temperature and corrosion resistance, ensuring stable and long-term operation. During the manufacturing process, a keen focus is maintained on balancing cost-efficiency and processing technology to deliver optimal results.
The strategic deployment of fins effectively addresses the challenge of scaling on the inner walls of boiler superheater tubes. Scaling can severely diminish the heat transfer area of the tube walls, thus impacting overall heat efficiency. By incorporating fins, the heat transfer efficiency is notably enhanced, resulting in reduced operating costs for boilers through decreased fuel consumption and improved boiler performance.
Functional characteristics of boiler tube fins:
1. Increase heating area: The fins substantially augment the external surface area of the tube, enabling the smoke traversing between fins to transfer heat more effectively to the steam or other media inside the tube. This innovative design markedly boosts the heat transfer capacity per unit volume, thereby optimizing performance.
2. Improve heat transfer efficiency: An expanded heating area is intricately linked to an elevated heat transfer coefficient, facilitating a rapid and efficient heat transfer process. This enhancement is pivotal for maximizing boiler efficiency and ensuring precise steam temperature regulation.
3. Diverse structural forms: These fins come in various configurations, such as spiral shapes that continuously envelop the steel pipe, secured by high-frequency welding for durability and resistance to detachment. Alternatively, they can be separate circular sheets, which, despite withstanding isolated forces, may mitigate dust accumulation and eliminate dead corners in certain applications.
4. Membrane wall application: In water-cooled wall structures, the use of finned tubes forms a 'membrane wall.' This configuration not only augments the heating surface but also enhances sealing performance, significantly reducing boiler air leakage and elevating overall thermal efficiency.
6. Welding strength and stability: Premium quality finned tubes undergo rigorous welding strength evaluations, including pull-out force tests exceeding 200MPa. This ensures the stability and reliability of the welding joints, providing peace of mind in demanding applications.
7. Specific design applications: Tailored for excellence, double H-shaped finned tubes, with their distinctive design, offer superior heating surfaces and enhanced heat transfer efficiency compared to conventional finned tubes. These are especially advantageous in power plant boilers, industrial boilers, and flue gas waste heat recovery systems, delivering unmatched performance.
