The intricately designed fins applied to the boiler superheater tubes serve as a sophisticated structural component that significantly boosts heat transfer efficiency. These fins are instrumental in amplifying the heating area, thereby enhancing the rate of heat transfer. Constructed from premium materials such as 15CrMo, 12Cr1MoV, SA-210C, SA-213T91, and 30CrMoA, these fins boast remarkable resistance to high temperatures and corrosion, ensuring reliable and consistent long-term performance. The production process for these fins thoughtfully balances cost-effectiveness with advanced processing techniques.
The strategic application of fins efficiently addresses the issue of scaling on the internal surfaces of boiler superheater tubes—a common problem that diminishes heat transfer efficiency by reducing the tube wall's heat transfer area. By employing fins, boilers benefit from reduced fuel consumption and enhanced operating efficiency, leading to substantial cost savings and improved performance.
Functional characteristics of boiler tube fins:
1. Increase heating area: The addition of fins dramatically expands the surface area on the exterior of the tube. This design allows the smoke traversing between the fins to transfer heat more effectively to the medium within the tube, typically steam, thereby significantly boosting the heat transfer capacity per unit volume.
2. Improve heat transfer efficiency: An expanded heating area correlates directly with an elevated heat transfer coefficient, ensuring a rapid and efficient heat transfer process. This enhancement is vital for maintaining optimal boiler efficiency and precise steam temperature regulation.
3. Diverse structural forms: Fins are available in various configurations, such as a spiral shape that continuously encircles the steel pipe and is secured with high-frequency welding for firm attachment. Alternatively, separate circular sheet-shaped fins, though subjected to singular force, can mitigate dust accumulation issues and eliminate dead corners in specific applications.
4. Membrane wall application: In water-cooled wall structures, the use of finned tubes constitutes a 'membrane wall,' which not only augments the heating surface but also delivers superior sealing performance. This innovation reduces air leakage in boilers, thereby boosting overall thermal efficiency.
6. Welding strength and stability: Top-quality finned tubes must pass rigorous welding strength assessments, such as pull-out force tests exceeding 200MPa, to guarantee the welding part's stability and reliability.
7. Specific design applications: Illustratively, double H-shaped finned tubes, with their distinctive design, outperform standard finned tubes by offering higher heating surfaces and superior heat transfer efficiency in environments like power plant boilers, industrial boilers, and flue gas waste heat recovery systems.
